about:config

[chinwag_]

How can I run 'about:config' (or something like that) to find Clearly's variable called "extensions.readable-by-evernote.keys_speech".
In Polish standard keyboard layout right ALT + S is used to enter a special Polish letter 'ś'. So when I for example compose an email in Gmail and try to write this letter Clearly Text To Speech page is shown instead and makes the extension unusable.

Not sure if it's the solution you're looking for but you can always make a script with Autohotkey that will override Clearly's keyboard shortcut
