Version: (using KDE 4.1.0) Installed from: Ubuntu Packages There is currently no way to select folders in Kmail via the keyboard. One must first change the current folder (via ctrl+left/right) and then select the chosen folder (via ctrl+space). For clarification, see Comment #1 from Bug# 165422 in which Thomas McGuire explains the situation.
Thank you for your feature request. Kmail1 is currently unmaintained so we are closing all wishes. Please feel free to reopen a feature request for Kmail2 if it has not already been implemented. Thank you for your understanding.
Instead of creating a new feature request, please confirm here if the wishlist is still valid for kmail2.
