Alt+ commands with gnome

After i've got the game working, i run into difficulties with the Alt key. Namely, Alt-click does nothing. I suspect it is a system settings issue. Anyway, how can i confirm/disapprove that, change Alt to something else either in Gnome settings or zero-k ones?

I don't know about in Gnome, but in XFCE you can make it work by going into settings manager > window manager tweaks > accessibility and setting "key used to grab and move windows" to something other than alt.

/grabinput in spring is superior to disabling alt-drag in your DE. I always miss alt-drag when forced to endure windows or macos...

Evolution RTS had /grabinput by default (via widget) and it caused me some ire.

Example of bad grabinput:

1) Anarchid starts an Evo game in borderless windowed mode.
2) While it loads, Anarchid goes from Spring-occupied virtual desktop #4 "Water" to Firefox-occupied virtual desktop #2 "Fire" and reads article about robot suicide.
3) Spring completes load.
4) Grabinput takes force.
5) Invisible window on hidden virtual desktop prevents all input to system. Good luck if you know how to quit spring blindly.

That is probably something that could be handled if focus is known. That is, set /grabinput the first time the Spring window gets focus, rather than when the game starts regardless of focus.

I'm curious if Forb is on Windows or Linux, since Windows doesn't really have virtual desktops (there are programs, but nothing native) while pretty much all Linux desktops and Mac OS X have them natively.

Are you running with Fullscreen, Windowed, or Borderless Window? "/grabinput" is a command you type into chat (or bind to a key in Spring/LuaUI/Configs/zk_keys.lua) which prevents the cursor from leaving the Spring window, at least while the Spring window has focus (I'm not fully sure how the behaviour differs between Windows and Linux).
