Can’t be bothered to remember all those pesky keypresses? Nor me. So why not remember just one?
control+alt+shift+c, control+alt+shift+c: choose any command.
Running this command will give you a list of every command that sublime text can run, from all your packages. It uses the quickpanel, which has very neat filtering and search behaviours, so you can easily find what you need.
