I want to customize shortcuts in Thunderbird using [https://github.com/wshanks/tbkeys tbkeys] but I can't find the right command name. In the description is written: "Most command names can be found in [https://hg.mozilla.org/comm-central/file/tip/mail/base/content/mainCommandSet.inc.xhtml the main command set file] of the Thunderbird source code." But where I can found all/ more/ other command names? In my case I want to change: * "Move to previous UI element" (default: Shift + Tab) * "Move to next main UI area" (default: F6) listed in this [https://support.mozilla.org/en-US/kb/keyboard-shortcuts-thunderbird?redirectslug=keyboard-shortcuts&redirectlocale=en-US#w_moving-around-thunderbird overview]
