I used to use the HUD in Thunderbird to move email messages to different folders. I found this a useful feature in Ubuntu 12.04 as I have a lot of email folders and it is quicker to use the HUD than using the right click menu to navigate through all of my folders. I simply needed to press 'Alt' to bring up the HUD and then type "move to " (actually you could shorten this further to "mo ").
I've recently upgraded to Ubuntu 14.04 and this no longer seems to work. I can still access the HUD and complete actions such as "New message" but I can't move messages to other folders.
Does anyone know why this is and if it is possible to get this functionality back?
Thanks for your help.
