Xterm and CURSOR (INS && OVERRIDE)

Xterm and CURSOR (INS && OVERRIDE)

[heiko_elger]

Hello,
my ZSH version is 3.05 and 3.1.4


Is it possible to send an escape sequence when pressing the INS key to change 
the cursor in the XTERM (AIXTERM), e.x. INSERT MODE --> full cursor, OVERRIDE 
MODE small cursor.

Sorry, I'm that this is perhaps a faq but I cannot find any info about this 
problem.

best regards

  Heiko Elger

This shouldn't be a problem.  The usual trick applies:  use ^V, then
the INS key to see what escape sequence it's sending, then bind that.
In my case the incantation is

bindkey "^[[2~" overwrite-mode

Sorry, I realise I misread that.  You don't just want to go into
overwrite mode, you want the cursor to look different, where I can't help.

In 3.1.4, this should do it; you may need to swap vs and ve, or use some
other termcap sequence, to get the cursor you want in each case:

	INSkey='\e[2~'	# The sequence sent by the INS key

	function overwrite_change_cursor {
	    bindkey "$INSkey" insert_change_cursor
	    zle overwrite-mode
	    echotc vs
	}

	function insert_change_cursor {
	    bindkey "$INSkey" overwrite_change_cursor
	    zle overwrite-mode
	    echotc ve
	}

	zle -N overwrite_change_cursor overwrite_change_cursor
	zle -N insert_change_cursor insert_change_cursor

	function precmd {
	    if [[ -o overstrike ]]
	    then
		echotc vs
		bindkey "$INSkey" insert_change_cursor
	    else
		echotc ve
		bindkey "$INSkey" overwrite_change_cursor
	    fi
	}
