The file into which changes in the availability and visibility of commands in the fixed and dynamic menus are recorded.
The buttons file is written to disk when you quit Praat, and it is read again when you start Praat the next time. It is a simple Praat script that you can read (but should not edit) with any text editor.
To add a command to a fixed or dynamic menu, you typically use the ScriptEditor.
To remove an added command from a fixed or dynamic menu, you typically use the ButtonEditor.
To hide a built-in command from a fixed or dynamic menu, or to make a hidden command visible, you typically use the ButtonEditor.
The buttons file is in your Praat preferences folder.
On Windows the file is called Buttons5.ini, for instance C:\Users\Miep\Praat\Buttons5.ini.
On MacOS it is called Buttons5, for instance /Users/miep/Library/Preferences/Praat Prefs/Buttons5.
On Linux it is called buttons5, for instance /home/miep/.praat-dir/buttons5.
