I migrated from icingaweb to icingaweb2 and now I am missing the option to force multiple checks.
Maybe I am just blind, but with icingaweb1 it was very intuitive.
After outages it is very helpful to force all failed checks to get a quick overview if everything came back online properly.
Mark your hosts/ services with Shift or Control and use the “check now” button
It works! Great!
Is it documented anywhere?
Thanks!
I do not know that. 
Please mark the answer as solution and have fun in icingaweb2 
At the moment, there’s no user interface documentation as the many parts should be self-explaining. AFAIK there’s a tooltip somewhere.
Typically users ask in here or have found it already
Found it (after searching the HTML source code):
