'w' moves forward by a word. 'W' moves backward by a word.
'I' inserts text by calling the "I" command from the Block
editor.
'I', 'F' and 'E' invoke the corresponding command from the
Block Editor (B100). Refer to documentation there.
'X' deletes "modifier" characters following cursor.
'R' goes into replace mode at current cursor position.
Following keystrokes replace current character and advance
cursor. Press return to return to normal mode.
