Meanwhile back on topic, I wanted to follow the same procedure for two other things:
1) windows + m (minimise all, i.e. show desktop)
2) windows only (start button opens menu)
Now then, without wanting to be a nuisance Windows fan boy, and not for want of trying, I looked and looked but couldn't get these using the same method.
Any tips to aid me in my perpetual quest to try and solve a linux issue by myself?
The Win+M should be easy, show desktop is on the list for things you can assign key binding to. I also recommend assigning that under edge bindings for bottom right corner click.... although I have that set and it technically takes two clicks, not sure why.... first one minimizes the current app, second click shows the desktop... maybe the same problem with a key binding? If you've already tried binding something, double check it doesnt work if you press it twice as may be the same problem and workaround are the same as with mouse. Also dont forget ctrl+alt+i is minimize current window, unless you can assign something easier to remember I also assign alt+f4 to close window because used to it from windows, etc, and dont use virtual desktops.
Menu key already opens the menu wherever the mouse happens to be (although you can use it with arrows/enter), but I do not think Bodhi allows changing key bindings for single keys or has a way to bind something to open start menu from start button (like windows ctrl+esc). You cannot assign the Win key to do something by itself within Bodhi. Win+Space already opens the everything launcher. Since you can click anywhere at all i never bothered to learn key bindings for the start menu, since I only use it with the mouse; if I'm typing I use everything launcher, which can also be opened with win+space by default...
if you really wanna assign the Win key to do something else, I think you'd have to go a step back from Bodhi, to linux keymap layout type stuff, and make the win key into the menu key.
Also report back with details whats going on with win+m=show desktop, should be the same as win+e for command=pcmanfm.
Menu key is the key between right alt and right control on most keyboards. Sometimes looks like three horizontal lines. I should have mentioned that earlier cuz that key is not labeled etc some people never use it or know what its for. Although android uses it. But most people dont use android with a 102 key keyboard. But yeah thats one of the three standard android UI buttons.
