Version: 4.12 (using KDE 4.1.2) OS: Linux Installed from: Ubuntu Packages One of the available keyboard shortcuts in Konqueror is labeled "Home" in the list of hotkeys. If this shortcut is set to "Alt + Home", it functions as you would expect: hitting that combination changes the current tab to your homepage. However, if it is set to "Ctrl + Home", a new tab will be created in the background with your homepage, while leaving the current tab unchanged. This is unexpected. Changing the current tab is what one would anticipate. If you have both "Ctrl + Home" and some alternative hotkey set, the alternative works properly while "Ctrl + Home" still opens the new tab. Perhaps it is something relating to the Ctrl key?
CTRL + Home is hard coded in Konqueror's code to open the request in a new tab. That is why assigning it as a shortcut key for the Home action does not work as you desire. I do not think this will be changed since it has been that way for a long time. However the fact that attempting to assign a CTRL+Home does not result in a warning is indeed a bug.
