In your sublime text keymap, add:
{ "keys": ["ctrl+1"], "command": "fold_by_level", "args": {"level": 1} }, { "keys": ["ctrl+2"], "command": "fold_by_level", "args": {"level": 2} }, { "keys": ["ctrl+3"], "command": "fold_by_level", "args": {"level": 3} }, { "keys": ["ctrl+4"], "command": "fold_by_level", "args": {"level": 4} }, { "keys": ["ctrl+5"], "command": "fold_by_level", "args": {"level": 5} }, { "keys": ["ctrl+6"], "command": "fold_by_level", "args": {"level": 6} }, { "keys": ["ctrl+7"], "command": "fold_by_level", "args": {"level": 7} }, { "keys": ["ctrl+8"], "command": "fold_by_level", "args": {"level": 8} }, { "keys": ["ctrl+9"], "command": "fold_by_level", "args": {"level": 9} },
Level 1 is fold all. Match the "," in your JSON to work. Done. ;)
