Version: (using KDE KDE 3.2.0) In KMail, the keyboard shortcuts are not always obvious from inside the interface, and the real shortcuts don't always correspond to those specified in the documentation. For instance, Previous folder (Ctrl+Left) and Next folder (Ctrl+Right) commands are not listed in the Go menu, so the user has to open the documentation to check those (and if they were modified, there is no way to tell without opening the shortcuts editor). Add next message to selection (Shift+Right) and Add previous message to selection (Shift+Left) should be listed in the Edit menu. It should also be possible to modify the keyboard shortcuts for these last two commands (they are not currently listed in the shortcut editor). Also, when moving from folder to folder using Ctrl+Left and Ctrl+Right, the documentation says to use Ctrl+Space to enter the folder. In my setup, pressing any key (including only Ctrl, Enter, and alphanumeric keys not associated to shortcuts) enters the folder. Only one (configurable) hotkey should do this. Finally, the Ctrl+Up and Ctrl+Down shortcuts (to enter the previous or the next folder) aren't documented anywhere. I think the Go and Edit menus should be extended to make all these shortcuts more obvious and configurable.
Olivier, thank you for your detailed report. Sometimes these small usablitity things tend to get out of scope of the developers, It's good that you gave us a reminder.
Please also use a KAction for "Read Message" so I can assign a keyboard shortcut to it. Quite important because without it, KMail is unusable without mouse with the preview pane disabled. (and I've got too many friends with RSI symptoms to call this "minor", btw)
good hint to use KAction, also for keyboard prefered users. The "[Oo]" - key or in combination with "Ctrl" (like normally used for open (intuitiv usability)) could be an idea?
In 1.10.1, the default next folder key (Ctrl++) and previous folder key (Ctrl+-) only change the window title using the folder name, but the folder selection is not changed. Also, the read message key seems to be Enter.
Thank you for taking the time to file a bug report. KMail2 was released in 2011, and the entire code base went through significant changes. We are currently in the process of porting to Qt5 and KF5. It is unlikely that these bugs are still valid in KMail2. We welcome you to try out KMail 2 with the KDE 4.14 release and give your feedback.
it's a lot easier to configure your own now, i'm happy :)
