I am used to using Ctrl+Alt+Up
and Ctrl+Alt+Down
as shortcuts for this operation. To make it work in Linux, you have to do two steps. First, need to disable system wide shortcuts by typing:
gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-down "[]"
gsettings set org.gnome.desktop.wm.keybindings switch-to-workspace-up "[]"
Logout and login afterward. Source: https://gist.github.com/michfield/5614949
Second step is to edit the Sublime Text configuration file, and change accordingly. I assume that everybody know how to do that. Just in case, add this in Preferences / Key Bindings - User
// change column select defaults - on Linux it was Shift+Alt+Up/Down
{ "keys": ["ctrl+alt+up"], "command": "select_lines", "args": {"forward": false} },
{ "keys": ["ctrl+alt+down"], "command": "select_lines", "args": {"forward": true} }
Tested on Mint 15 Cinnamon (RC), based on Ubuntu Raring.
