[PATCH] Main menu hotkeys

[elexis]

It would be nice to control the mainmenu from keyboard (instead of being forced to move the mouse). For example:

M - open multiplayer menu
 L - open lobby
 H - host game
 J - join game

M might be used both for Singleplayer -> Matches and Multiplayer. It should just check for the currently opened submenu. The current submenu can already be closed using escape Maybe we could also have a hotkey like ctrl+escape to close the gamesetup/lobby? See also:

Hotkey for clearing the lobby chat was discussed in #3396. For building hotkeys #1492, it was suggested at some point to allow the user to set hotkeys in the GUI. May or may not be needed here. Having them in defaults.cfg would be a good start.

Certainly not simple since this whole thing does not seem useful, the whole hotkey choices need some discussion and I'm inclined to just close this as invalid.

• put these default.cfg entries to hotkeys.mainmenu, they have nothing to do with overlays
• some unneeded parenthesis
• don't call the hotkeys according to their key. The idea behind hotkeys is that the user can change them. So if mainmenu.toggle_s can be assigned to the J key, that name doesn't make much sense. The names should be specific towards what they do, i.e. hotkey.mainmenu.multiplayer and hotkey.mainmenu.multiplayer.connect
• The user must know that these hotkeys exist, so it should be displayed in a tooltip.

Backlogging due to lack of progress.

Move tickets to Misc. UI as "UI & Simulation" got some sub components.
