trivial question - multiple selection of clients ?

[tiberius]

Hello folks,

I'm kinda new to opsi and I really like the way it goes - Currently I'm still testing opsi on centos 7 anyway.....I have quite trivial question:
How can I select multiple clients to set actions for all clients at the same time - eg. setup. java for example !?
I saw a opsi video where the guy selects multiple clients on the left handed side, I tried many different key combinations without success
EDIT > I know that I can do it with define search but is it possible to select multiple clients manually ?

Thanks in advance - Best,
Tiberius

Hold shift or control while selecting clients.

does not work here - seems to be an osx reletaed java issue- not solved yet.
