Bash: invoking a script using special keyboard shortcuts?

Question

Suppose I have a script, " myscript.sh", and the content is simple echo $PWD. I would like to somehow attach this script to a key combo in bash( gnome-terminal) - so when I press this key combination, the output is " myscript.sh" inserted ("inserted") at the cursor position in the terminal.

Apparently the bashstory and line manipulation are handled by readline - and the links I got for the bashshortcuts make a link readline:

• bash keyboard shortcuts
• bash Reference Guide: Related Readline Commands

I also saw in the bash Reference Guide: The syntax of the Readline initialization file that key bindings for bashcan be listed in using bind -p(see help bind[not 'man bind'] for more). Therefore, perhaps this question is better called "_binding macros to custom key combinations in readline" :) But in any case, is this what I want to do?

I suppose an alternative would be to have a script something like " pwd | xsel -b", and then I call it on the terminal - and then I can paste it; but I still would like to use only one key combination, for example Ctrl-Alt-H (which, it seems, is not used for anything), which immediately inserts / inserts script output when pressed.

Thanks in advance,
Hooray!

I was only dealing with programmable completion, so I cannot give you the details, but the above bash_completion package or the completion of a subversion script may be a good start.
