location_popup
Description:
The location_popup signal is a keybinding signal which gets emitted when the user asks for it.
This is used to make the file chooser show a "Location" prompt which the user can use to manually type the name of the file he wishes to select.
The default bindings for this signal are `Control + L` with a path string of "" (the empty string). It is also bound to `/` with a
path string of "`/`" (a slash): this lets you type `/` and immediately type a path name. On Unix systems, this is bound to `~` (
tilde) with a path string of "~" itself for access to home directories.
Parameters:
| path |
a string that gets put in the text entry for the file name |
