According to the documentation for Linux column select uses the following commands:
Linux
Ctrl+Alt+Up
Ctrl+Alt+Down
but on Ubuntu 12.04 with Cinnamon (not tested on Unity) this triggers the window switching operation (part of Cinnamon).
Anyone have a good fix for this (other than using the mouse...)
Thanks,
Think that documentation is wrong. Just did a quick look into the Default (Linux).sublime-keymaps (which you can access from Preferences -> Key Bindings - Default but that's besides the point), and it looks to be alt+shift+(up/down). I was going to recommend rebinding the keys (thus the reason I was looking) but this may also solve your problem. =) Not tested, just based on the keymapping file. If that doesn't work, let me know.
