How to disable Command + Left keyboard shortcut in Yosemite CMD + LEFT is a really important shortcut that i use in multiple applications on my mac: (go to back in google chrome, to put the cursor in the beginning of line in any IDE...etc.). however, it seems that in Yosemite(?) this command seems to move my window left.

how do i disable this keyboard shortcut? (same with CMD+RIGHT)

i looked in mission control and system settings keyboard, but couldn't find anything
Nevermind. i found out why - apparently someone installed BetterSnapTool on the server, which does this.
