in past few days, i made another majorish change to my emacs keybinding set.
Now personal global commands start with F5. (used to be 【Ctrl+l】) Personal mode-specific commands start with F8. (used to be 【Ctrl+e】) (this is on Dvorak)
the gist in the change is that i now use single key sequence instead of combination.
over the years, i gradually switched almost all my most often used commands to single key or single key sequences, instead of combo keys or combo-key sequence.
if you type a whole lot, and experiencing hand discomfort, then single key is healthier than combination keys, even if it means a fraction of second slower to reach the F keys.
working in emacs now is like hunt'n'peck. LOL
