This is an introduction to the vi family of editors.
In Hebrew.
I just thought about it, so I don't have any specific plans, but maybe this becomes a whole series of videos if there is interest. a means we move to edit mode starting to append text
a - append
i - insert
O - edit mode inster new line above current line
o - edit mode inserting new line below
A - append at the end of the file
ESC - back to bbasic mode
ESC :wq - write (save) and quit (exit)
ESC :q - quit
ESC :q! - quite without saving
dw - delete word
u - undo
x - x delete the current character
$ - jump to end of line
d$ - delete till end of line
