Browser shortcut/accesskey s doesn't work and e/p are missing

Question

Follow-up of https://www.wikitree.com/g2g/1039532/greasemonkey-scripts-for-shortcuts-etc :

When editing a profile the html source code contains two buttons labeled with accesskey='s' which will lead to them only receiving focus when pressing ALT + SHIFT + s instead of triggering the button.

It also would be nice to have accesskey 'e' for editing and 'p' for preview, since I'm used to it from other MediaWiki installations.

Until the website is fixed I patched it with this Greasemonkey script: https://github.com/FlominatorTM/WikiTree/blob/master/Greasemonkey_Shortcuts.js

Kind regards from Black Forest
