In Sublime Text 2 it was possible to comment out a line or a block of lines with Ctrl+/ and Ctrl+Shift+/. According t
You can add the following lines to Preferences / Key Bindings - User:
{ "keys": ["control+keypad_divide"],"command": "toggle_comment", "args": {"block": false} },
{ "keys": ["shift+control+keypad_divide"],"command": "toggle_comment", "args": {"block": true}}
This is how I sorted the problem out - replacing "ctrl" with "control" and "/" with "keypad_divide".
