Yes, if you just do an empty tsr with no parameters it'll create a 'next' entry by default which marks a new task.

You can 'come back' to the previous task (or rather start it again) by typing the same tags into tsr.

   tsr work feature 1425
   tsr
   tsr work feature 1425

the empty tsr in the middle creates 'next' in the record.

It's not technically a pause as tsl will display the duration of the latest entry only, but if you aggregate it later it'll all sum up.
