When you create a new Terminal window it will launch a new shell that logs into the local machine. This happens when you create a new window or a new tab.
There is no way to have the shift-command-K behavior open a new tab, but you could possibly create the tabs and then manually use "ssh username@domain" to connect for each tab instead of the "New remote connection" window. This would have you using only command-T, but would be cumbersome in having you enter SSH parameters yourself.
I regularly connect to lots of remote machines via SSH. I prefer to have them all in tabs rather than separate windows.
There's a cmd-T shortcut to open a new tab, but only for the local machine. At present I have to go shift-cmd-K, open all the tabs, then go to Window, Merge All Windows (no shortcut for that) to bring them together. I tried 'Window groups' but again this just seems to create multiple local connections.
Is there a hidden way to auto-open everything in tabs, or just reduce the number of keystrokes?
Thanks in advance,
