Yep. Center button hold is a good choice. Also, you can launch TealMASTER by a stroke, T3 closed, from Home toward screen with TealLaunch Open, and "launch TealLaunch" by tapping the Home menu once.
Set up taps/strokes as follows:
Tap home once - TL menu. Tap again - takes you back to apps. In other words, tap twice to in the same place, tap and hold and the default "Palm last used" menu still pops up.
Center button hold - TL menu.
Stroke from "little house" to screen to launch TealMaster. I have that same stroke with TL OPEN launch YAHM (I use both managers for different hacks).
I find this gives you quick options for both, although once configured TMaster and YAHM don't really have to be messed with unless your're trying a lot of hacks.
This relates to my "ScreenButton" post; once the TL menu comes up, if the bottom most entry is ScrnButtn, you've got another entire launcher at hand.
