General tab key problems throught Zimbra web UI
It seems to me that the Zimbra web UI has fundamental problems relating to the behavior of the Tab key.
Oddly, I don't find much on this when searching the forums, but there are several related bugs. So I don't know if this means most people don't care, or these forums are mostly visited by systems admins who don't care...
Personally, I find it annoying and embarrassing, it makes Zimbra look buggy and incomplete in the eyes of my customers.
So, the solution is for people to create bugs and or vote for existing bugs. This is the only way the Zimbra development team can determine what is important to the community.
Having said that, here is a list of existing bugs related to this issue.
4336 - Hitting tab in mail compose window moves cursor to incorrect position
4435 - admin ui new account dialog focus (shift-tab)
4874 - Tab out of appointment auto complete does not go to next line
9460 - Unexpected tab key behavior in Admin dialogs
10027 - KBNav: limited focus landings when tabbing through options
10404 - tab order FF 220.127.116.11 on Mac OS X
10494 - Tab order not working for create new account pane
Go look at the bugs, and if they are happening for you in current versions of Zimbra - Be sure to vote for them!
