Version: 1.9.9 (using 3.5.9, Debian Package 4:3.5.9.dfsg.1-2 (lenny/sid)) Compiler: Target: i486-linux-gnu OS: Linux (i686) release 2.6.24-2.6.24.3.slh.6-sidux-686 Often it is quicker to navigate in applications with the keyboard instead of with the mouse, especially when you in any case have to use the keyboard to write text. Kmail is one of those programs. When I click into the folder list I expect to be able to scroll up and down by using the cursor keys. When I click into the mail list I expect to be able to scroll it with the cursor keys too. But both does not work, instead of that the mail in the mail preview window is scrolling. When I want to scroll the mail I'd first click into its window (or use tab to activate it). At least other programs with divided window handle the internal navigation this way (thunderbird, quanta, kooka - just to mention a few). Now that kmail has become an enterprise capable version I'd expect even more to have a consistent behaviour and to honor those fast typers - and those who have difficulties or don't like to use the mouse for everything. I'd consider it to be a bug not to be able to scroll through my kmail folder list and the list of mails with the keyboard cursor keys, but as I assume it is a feature/intended behaviour I mark it as wishlist entry.

If you use the mouse to click into the pane you can continue using the mouse. If you want to jump to the next unread messages, there are shortcuts, CTRL++ I think. If you want to jump to a folder, there is "j" as shortcut. If you want to navigate the message list: use right-cursor for "next message" and down-cursor for "scroll down message-text". Using both, up and down, as well as left and right is far more comfortable because it saves you a lot of clicking or tabing in order to change between the message-list and the preview-pane.
