Hello,
I apologize, english is not my native language and most likelly due to
this you were unable to get my point.
We currently have shortcut keys where the same key is used multiple
times. Once with capslock only and second time with both capslock+ctrl
as modifiers.
I am sorry that I am too picky but please try to transform all the
following shortcuts one after the other the way you wish to have them
implemented so we will not cause conflicts.
capslock+right navigate forward
capslock+left navigate backward
capslock+up decrease granularity i.e. change from word to character
capslock+down increase granularity i.e. change from character to word
capslock+ctrl+right scroll forward
capslock+ctrl+left scrol backward
escape same as pressing the back button
capslock+escape same as pressing the home key
capslock+ctrl+up open notifications
capslock+ctrl+down start say all
