Thanks stalker48, nirwana, and MatrixIsAllOver!
I'm going to add your locales to the next release.
About the shortcuts keys:
I understand ALT, SHIFT and CONTROL, but what is meant by Accel and Meta ?
These sound to me like Mac OS, but do other platforms have these equivalents ?
Accel key varies depending on OS. For example, the key refer to CONTROL key on Windows, ALT key on Linux.
For more information, see XUL Tutorial.
Meta key is the key on which diamond is printed. The key exist in the keyboard for UNIX environment.
Users should use modifiers exist in their environment because modifiers are platform-specific.
Where can I find the Jump-translations ? I can translate them, but where do I find them in the user interface ?
The functionarity is located on the message pane and the thread pane context menus and the toolbar button which is labeled "Jump". You can change folder selection by the functionarity.
