Triggering the UVM Field Editor for a certain class: place the cursor anywhere inside the class definition, right click and select Source > UVM Field Editor from the pop-up menu. If you place the cursor on a field, the UVM Field Editor will show up with the respective field selected.

If there are no previously registered macros, the uvm_*_utils_begin and uvm_*_utils_end macros shall be determined based on the class found at the cursor position. For a class that inherits from uvm_sequence, a pop-up dialog will ask you to select the desired sequencer from the available ones.
