Version: 4.5.9 (using 3.5.9 "release 53.4" , openSUSE ) Compiler: Target: i586-suse-linux OS: Linux (i686) release 2.6.18.8-0.7-default intendation using CTRL+I works moving intendation backwords usign CTRL+SHIFT+I has no effect at all. Using the feature from the menu works.
Check, whether you have kopete running and the global shortcut activated: 1. open kopete 2. Settings > Configure Global Shortcuts 3. Read Message has the shortcut Ctrl+Shift+I by default. Remove it, if you don't need it. If this is the case, then this is a duplicate of bug #80837.
Reminder, could you please verify the steps as described in comment #1 ?
Without feedback I'll just assume this is a dupe of bug 80837. *** This bug has been marked as a duplicate of 80837 ***
