If I have 2 events butted end to end on a track and want to create a precise 45 frame crossfade by the dragging method, how do I get that precise frame count?
Position the cursor at the end of the first clip (easy to do with Ctrl-Alt-arrows) and note the frame number in the preview window. Subtract 45 from that and move the cursor to that frame (left arrow moves back a frame at a time, or you can guess with the mouse and then use the arrow keys to get the exact spot). Leave the cursor there, and drag the second clip back; it will "jump" to the cursor position when you get close enough.
use ALT+ARROWS when you want to move frame-by-frame and make sure snapping is turned on, but not snap-to-grid, to ensure that after you place the cursor, you can easily snap the other event to it.
cheesehole: good point. I forgot about the Alt, but in version 3.0a moving by frames is the default action for the arrow keys now.
Also, to be precise (and i always love being precise), one needs to subtract one less than the desired number of frames since the last frame is included in the crossfade. So if you want a fade of 45 frames, subtract 44. (Go ahead and scratch your head. Draw a series of boxes on a piece of paper, number them, and count them off. It makes sense once you see it.)
You may also go into Options > Preferences > Editing and set your Cut-to-overlap amount to 45 frames (1.502s). When you drag clips over the top of each other, this is an additional snap point, to get consistent, repeatable fade durations using the mouse.

Transitions: Put cursor between events, and use "/" or " * " or "-". Look up "Convert a cut to a transition" in help for more info. you'll find it there if this shortcut isn't what you need.
