So basic keyboard navigation is still broken, right?
Gonna have to be more specific, I fear.
Left arrow moves left, Right arrow moves right, Home returns to the beginning of the tab, then beginning of the line. End takes you to the end of a line. Ctrl+arrows jump by a word, Ctrl+shift+arrows select by a word. Afaik, the only one missing is Ctrl+shift+End to select to the bottom of a script? (Ctrl+End jumps to the end of a script).
Ctrl+Shift+Number sets a bookmark, Ctrl+Number jumps to it. Ctrl+ALT+Arrows moves focus to adjacent code windows/ Ctrl+PgUp/PgDn changes tabs within a code window. Middle Mouse and drag pans around the workspace...
Many things are working, particularly in the area of "basic" keyboard navigation. They've definitely tweaked a lot of that lately... Heck, they even fixed the issue where pressing Ctrl+C with nothing selected cleared the clipboard.
