Unfortunately there are other plugins that use "ctrl + alt + f", this is a hard problem to solve. If JsFormat works OK via the command palette but does nothing when you use the "ctrl + alt + f" shortcut, you have two options:Add { "keys": ["ctrl+alt+f"], "command": "js_format"} to your user keybindings file. This will override anything specified by a plugin.Find the offending plugin, and change the shortcut in its sublime-keymap file (will revert on updates)
或者：
Open the command palette via "ctrl + shift + p", Jsformat appears as "Format: Javascript"
