From the main FAQ:

"28. Why is my video track split between "A" & "B" tracks?
If a red square bracket appears at the end of one of your video events then you are in Expanded Edit Mode. To exit expanded edit mode, do one of the following:

Choose "Edit" > "Select" > "Exit Expanded Edit Mode"

Press 5 on the numeric keypad

Double-click the event edge

Press Esc on your keyboard
 

If no red square bracket appears then your track layers are simply expanded. To "unexpand" them, right click on the track header (the area to the left of the track) > uncheck "Expand Track Layers"."

Thanks but that wasn't the question. In fact, pressing 5 on the numeric keypad, double-clicking the event edge or pressing Esc does nothing. I also DON'T want to keep unchecking Expand Track Layers.

I'm looking for a way to disable this feature entirely because I'm not working in A/B mode and I don't want it getting in the way.

Dexcon, thank you. It doesn't make sense. If this has been an issue all these years then why has it not been dealt with already? Surely, it can't be that hard to program in a "don't do it" function if it's been switched off in preferences - or even just a toggle key to enable/disable the feature (like they've already done with ripple editing)?

I'll contact tech support directly. It's obviously something that they have to escalate internally - and they've probably never bothered to read the user forums during all this time. Disappointing!

PS Maybe there's a third-party add-in that can override it in some way. I'll get in touch with the developers of Vegasaurus. It's the sort of thing that could probably be quite easily "programmed out".

Sorry, it cannot be disabled.

@gary-o, is it possible your mouse button is getting a bit "bouncy". I have a mouse where the right-button would sometimes double-click even though I pressed it only once (it would sometimes paste two copies of what was on the clipboard into a terminal session). Adjusting the Windows double-click speed didn't fix it. I could have gone out and paid $20 to get a new mouse, but instead I pulled it apart, squirted some contact cleaner into the button, and it's good as new!

You don't accidentally "Expand Track Layers", but you may accidentally enter "Expanded Edit mode". It does expand track layers, but the actual "Expand Track Layers" feature can be toggled in the dropdown menu when you right-click on the Video Track header.

When you make a Feature request, please use the terms that VEGAS uses. And yes, the VEGAS team has discussed this, please see this recent comment. @gary-o

Thank you. I didn't know the correct terminology. In the latest version of Vegas, it says "Expand Track Layers" on the video track header.So I presumed that inadvertently double-clicking on the edge of a clip when you're trying to trim it was the alternative mechanism to expanding the track layers.

It's not something I've noticed before, but in the last couple of upgrades, I've noticed this happening a lot - when I'm not wanting to enter "expanded edit mode". Maybe it is a mouse issue, so I'll look into that.

But when I searched for an answer to this problem, I see that it's been a user request for over 5 years now: to have an option to disable it. And in the link you provided, I see that it's already in there as a feature request.

Derek on the Magix development team, I presume, as stated that they will try to implement it in a future release. So hopefully it will be sooner rather than later.

On another note (should I raise a ticket for this?) why is it that neither Esc nor numeric-keyboard-5 doesn't function for me? Do I need to do something extra to enable these keys? Or are these keys only active on proper desktop machines / external keyboards? (I have an Acer laptop computer, and I think laptop keys behave slightly differently from external keyboards.)

But at least the Esc key should work. I noticed this before when I tried to cancel the opening of a project that I had opened inadvertently or because I didn't want to wait for the current project to reopen when first loading Vegas. However, pressing Esc to cancel the load doesn't work. Neither does clicking on CANCEL at the bottom of the screen. I usually just have to wait for the few minutes for the project to fully load and then close it manually.

Any ideas about that? Is it a bug?

Esc only works when the focus is on the timeline. It is unclear why this is sometimes not the case. With Alt + 0 you can set it on the TL beforehand and then press ESC.

Pressing 5 on the numeric keyboard is usually the easiest and quickest way ro restore the track layout.

Nick's FAQ (which I quoted above) mentions 4 ways to get out of the Expanded Edit mode. The OP says that 3 of those don't quite work for him, which is a bit of a mystery.

ESC and NUM + 5 only work if the inputs relate to the timeline, i.e. the focus is set to the timeline. If settings are made to an Event FX in expanded edit mode, the focus is to this FX and all key inputs refer to this FX until the focus is again to the timeline.

But there's a great function in the expand mode. When I double click the hard transition between 2 clips, I can adjust these 2 pictures/frames accurately as I desire.

Please go on keeping it Magix.

@Yelandkeil

It is really great that you appreciate this function and find it useful, but many users don't need it or want it. From the OP's issue, the question is how to turn it off so it isn't accidentally activated by double-clicking on the edge of an event. Yes, it is easy to recover from BUT all the track heights are re-sized from what they were before entering expanded edit mode - so then they all have to be re-sized.

There is no question that Expanded Edit Mode is a valuable feature, but there does need to be a way to defeat it for those who don't need or want it because of its susceptibility to accidental activation.

Pardon me if unpolite, but for what reason do/will you double click the end or anfang of an event if you don't want to edit/adjust them?

And, I only do this in the first phrase of edit (cutting, arrangement and fine coupling the events one by one). I barely use the other transitionFX.

OK, if Magix can find a way to satisfy everybody.

Please do note the difference between "Expand Track Layers" and "Expanded Edit mode" features. VEGAS Pro has both. Movie Studio Platinum had "Expand Track Layers" as well but it was dropped when VMSP 14 came out. It was a handy feature in MSP and I wondered about the decision here. I guess the real reason must have been the "product differentiation". The "Expanded Edit mode" was never in MSPs. To me it seems that @Yelandkeil likes ETL as well.

Pressing 5 on the numeric keyboard is usually the easiest and quickest way ro restore the track layout.

@Richard Jones - Hah! Thanks Richard. Now, all I need to do is remember it.

Thanks @vkmast for the clarification again. I assumed that the OP meant the "Expanded Edit Mode". But that's exactly where it can happen that ESC doesn't work, that's why I point out the focus on tImeline.
NUM + 5 is not available on a laptop without a numeric keypad, and those who double-clicked this mode do not necessarily remember NUM + 5.

I find this mode helpful and have no problem with it. But I think if it were not available by default and only switched on in the settings, it would make it easier for some users.

My question again: for what purpose do you double click the event edge? Inadvertently? then you made a mistake, you should correct it, like you erased something and must go to the trash if you want it back.

It's not nice saying "many users...", how many? give me a percentage pls.

In vegas movie studio this expand track layers was once gone away and "many users" protested till it came back (or not I don't know).

For me I find this design (1) aesthetically absolut a disaster, and the default surface (2) of the plugin must be so. But, that's my idea and not many users', so I try to accept. I do like Vegaspro so much.

The actual "Expand Track Layers" feature has not come back to the VEGAS Movie Studio Platinums. And the "Expanded Edit mode" has not been a feature in them, so no "Why is my video track split between "A" & "B" tracks?" "issue" in VMSPs. (See #28 in the FAQ)

The title of this thread should read "How to disable event edge double-click to engage Expanded Edit mode [in VEGAS Pro]".

There's an amazing survey in the forum: do you often cut event in other tracks accidently in Veg?

I would answer:

Many users will that Vegas-Team abolished this very pesky S-key-cutter and set an icon scissors on the timeline toolbar like the other NLEs.

How do you guys think?

"Many users will that Vegas-Team abolished this very pesky S-key-cutter and set an icon scissors on the timeline toolbar like the other NLEs."

This already exists (in the editing options menu of the timeline toolbar).

"Many users will that Vegas-Team abolished this very pesky S-key-cutter and set an icon scissors on the timeline toolbar like the other NLEs."

This already exists (in the editing options menu of the timeline toolbar).

And doesn't remotely solve the problem if the problem is that the wrong thing is selected when 's' is pressed.

And I'm glad there's an option but t00000x glad that it's not the default. I hate programs that don't have keyboard shortcuts for commonly used operations. Having to move the mouse is a billion times slower.
