Re: Cell bracket <-> Inline



hi Carl,

I'm puzzled by the Frontend's handling of these key events, and a bit
wary of getting hopelessly lost when medling about in these things. On
my machine, the insert as below doesn't work (tried it with Command and
Control as modifiers).
I have the impression that this part of the software isn't really
compatible with the "Microsoft Win'95 PC" type keyboards.

I have achieved an andvantage though : if I walk the cursor down (in
bracket selection) over a closed cell, it doesn't open up anymore.
That's good, I wanted that effect! (what the Lord has closeth, no
cursor movement shall openeth ..(;-))

Thanx for looking in to this,
wouter.

        . . .
	Item[KeyEvent[Up], "MovePreviousLine"], 
	Item[KeyEvent[Down], "MoveNextLine"],  (* added 24/01/98 mail Carl Woll
*)
	 Item[KeyEvent[Down, Modifiers->{Command}],
      FrontEndExecute[{
        
FrontEnd`SelectionMove[FrontEnd`SelectedNotebook[],After,CellContents]
      			}]  ],
(* end new key event from cell bracket to in-line selection *)
	Item[KeyEvent[Left], "MovePrevious"], 
	Item[KeyEvent[Right], "MoveNext"], 
	Item[KeyEvent[Right, Modifiers -> {Option}], "MoveNextWord"], 
	Item[KeyEvent[Left, Modifiers -> {Option}], "MovePreviousWord"], 
        . . .
