I'm making my own theme and tweaking a copy of default.thm, I want to change the Highlighting to Mask Overlay. Below is what the default.thm is set to, which I'm guessing "Block" actually stands for the "Rectangle" option in DVDA. So, what do I need to type in place of "Block" to make it do a Mask Overlay?
<HIGHLIGHTING>
<STYLE>Block</STYLE>
<COLOR>255, 255, 255, 128</COLOR>
</HIGHLIGHTING>
<HIGHLIGHTING>
<STYLE>Block</STYLE>
<COLOR>255, 255, 255, 128</COLOR>
</HIGHLIGHTING>
