Rated 5 out of 5 stars

Works well in Palemoon, no problems.
+ good outline by developer on the addons page is very welcome
(A lesson for developers of other extensions/addons
+ keeps my key-bindings to a minimum to free up for other extensions and OS global keys.
+ easy to manage other extensions, who overkill with shortcut keys
+ very easy to use ... simple common sense settings even for a dinosaur like me
+ "Options" window keys can be customized via "Keyconfig" item, I disabled the default Ctrl+Shift+F12
+ blue text for custom settings saves having to document my preferences
-- disabled settings by user cannot be identified ... bold font could help
+ reset btn resets the selected "key", thankfully it does not reset the entire list
+ worth a donation ... but where ?

Thank you for your time and effort, very appreciated :applause:
