how to swap clipboard content with selection upon keyboard shortcut

Question

I\'d like to exchange the currently selected text in eclipse (or even any program) on linux with the content of the clipboard when pressing a shortcut like Ctrl-B. Any ideas

Answer 1

found following solution using xvkbd:

• make sure following packages are installed: xsel xvkbd
• save the script below and bind it to a global keyboard shortcut like ^B. (in KDE I had to add it to the KDE-Menu first)

this is not very robust, e.g. when I tested it without the sleep command, the ctrl modifier key seemed to be stuck, i.e. the A key was interpreted as ctrl-A and I found no way to reset it. Otherwise this does what I want.

#!/bin/sh
# swap currently selected text with content of system clipboard, i.e.
# 1. save current clipboard content in oldClip
# 2. copy current selection into clipboard
# 3. print oldClip so that it overwrites previous selection
# this is supposed to work in eclipse but could work in other applications, too.
# usage: invoke this script via a global keyboard shortcut

# give user time to release keys, otherwise ctrl modifier might get stuck
sleep 0.5

# when run via shortcut stdin+stdout are redirected => xsel behaves differently.
# therefore always specify the mode explicitly.
oldClip=`xsel --clipboard --output`
xsel --primary --output | xsel --clipboard --input

xvkbd -text "$oldClip"
