The vi approach was to make the useful commands easy to type rather than easy to remember, hence hjkl to move the cursor instead of ldur, and ZZ to save changes. Once you've learned the keys there's no longer any advantage to mnemonics so why punish your fingers with unnecessarily awkward keystrokes? (Looking over the keyboard and seeing that just about every key has a useful function, it seems to me that the ultimate goal of vi evolution is for a cat to be able to walk across a keyboard and type nothing but valid editing commands.) -- Matthew Winn
