- open KBar Settings
- click Add Button > Set Expression, then give the expression a name and type the expression.
- click SAVE or click CLOSE.
--> unlike Scriptlets, there's no interactive (EXECUTE) mode, so what's the purpose of these names (e.g., SAVE not closing the dialog, CLOSE really cancelling changes)? am i missing some mode?
seems more consistent to have it as OK (and close immediately) and CANCEL, like most other dialogs for adding a button, at least the way expressions work right now.
