I'd like to add a hotkey for the menu item Edit>Permute Lines>Unique, but what I've added to my user keybindings isn't working:
[{ "keys": ["f8"], "command": "permuteLines method unique" }]
What should I have added?
Take a look at this question/answer: How can I set key bindings for menu items in Sublime Text 2?.
Add to your User keymap:
{ "keys": ["f8"], "command": "permute_lines", "args": {"operation": "unique"} }
