After finding an entry in the forums that ‘CTRL + SHIFT + 1-4’ will be able to call the Kee browser extensions, I was wondering if it is possible (yet) to alter the keyboard bindings? For Chrome this should be possible via the ‘commands’ API and with Firefox it should be possible via the ‘Keyboard’ API (which are probably already in use, as keyboard shortcuts are already implemented).
Amazing, I can confirm that the above comments work for both Firefox and Chrome. Additionaly, I can confirm that that the Kee browser extension for Chrome also works with the latest Chromium-based version of Edge (as well as the Edge for Business variant), which also supports modifying the keyboard shortcuts.
