'0' should jump to apps that begin with 0 (though there should be few, admittedly
-- space is a pretty safe key for me to steal (and mmenu has been stealing it since day one anyway).
Theres a lot of keys I'd like to swipe, but as soon as I added 'jump to letter' long ago, I lost a lot of them
It used to be a touch prettier even -- jump to letter -- if the app was a few screens down, it'd jump; a screen at a time which was sort of neat to see mmenu scrolling automagically for you, but now it just jumps straight to it -- which is faster, which is all about what mmenu is for.
I will be adding a help viewer down the road, but to do it depends on a few things outside of mmenu per se, so we're gearing up for it. (ie: viewing a _text_ in the pnd is one thing, but viewing _html_ or who knows what is another, so I want to handle it properly, which needs a few things first, yet.) But it'll come.
Regarding restarts -- in current mmenu betas (not sure which you're on) theres a config item that informs mmenu _not_ to quit on running an app; this was for Plengs idea of using mmenu as a launcher in a multitasking environment (ie: with a app-list at the bottom of the display say), so he didn't want mmenu quiting all the time. So you're already covered, but its best to do that with a app-bar running or somesuch, otherwise its just sitting there inthe background eating a bit of RAM and CPU; but it'll pop up when the last app exits anyway, so it'll work fine for you, if you just want to save on start up time. Try it out and see
(The design for mmenu was that it is very low on RAM and CPU usage -- while an app is being run, mmenu uses almost nothing (like, a few K of RAM is all, and no CPU since its not even running.) When the app exits, mmenu comes up.
mmenu can run without X11 or window managers or any of that, as well which makes this all pretty handy .. if a system is set up lean -- boot straight to mmenu without X11, it can run apps and you've got nearly your entire memory pool available to the app. Course, not having X11 up menas half your pnds will break, but such is your choice in that setup
