There are default popups… I rebound a lot of keys to match N++ as a lot of their keys were intuitive and I rebound a few for Sublime Text to the Function keys…
F1 through F12… I hate how sublime text now overwrites the User keybind file deleting all comments and making it ugly…

and it resorts…
You’ll want… the F1 key.
Note: F21 through F24 are not bindable in Sublime Text as of 3176… The other F keys are.
