I’ve been trying to get column selection via keyboard bindings working on Windows.
The Default (Windows).sublimekeymap says this:
{ "keys": ["ctrl+alt+up"], "command": "select_lines", "args": {"forward": false} },
{ "keys": ["ctrl+alt+down"], "command": "select_lines", "args": {"forward": true} },
And it is also documented here: http://www.sublimetext.com/docs/2/column_selection.html However, every time I try to do column selection via the keyboard it doesn’t work. Is this an environment specific problem or an actual bug? Or perhaps I’m doing something wrong.
Assuming you are getting multiple cursors when you go up in a block of text with Ctrl+Alt+Up, you then need to use Shift+Left and Shift+Right to make the column selection.
If you are not getting multiple cursors at all, try changing the keybindings just to
upanddown, see if that works. It may be that your windows environment is using Ctrl+Alt+Up` for something else and prevents its use in Sublime.
