I've edited the file Preferences > Key Bindings User, and added this:
[
{ "keys": ["ctrl+/"], "command": "toggle_comment", "args": { "block": false } },
{ "keys": ["ctrl+shift+/"], "command": "toggle_comment", "args": { "block": true } },
]
But the shortcuts doesn't work. What went wrong?
I solved my problem:
[
{ "keys": ["ctrl+keypad_divide"], "command": "toggle_comment", "args": { "block": false } },
{ "keys": ["ctrl+shift+keypad_divide"], "command": "toggle_comment", "args": { "block": true } },
]
Just replace '/' by 'keypad_divide'
