Version: (using KDE KDE 3.3.1) Installed from: Debian testing/unstable Packages It is quite good that akreagator can be completly used with a keyboard. But this takes a time to learn and also to be reminded about the possibility and how useful it is. So to promote the idea I would suggest to have the short-cuts displayed at the entry page and may be as tool tips. I know there are in the menues, but I know from me and other that I often do not register them there.
This is very atypical for KDE applications. You can learn the keyboard shortcuts in the Settings->Configure Shortcuts menu entry. Furthermore, keyboard shortcuts vary from installation to installation even. I can't imagine this ever being implemented.
