Function pinning
If there is a function of interest, it can be ‘pinned’ to the top of the function name list to ensure it is
always visible when scrolling left and right. This is done by left clicking the mouse on the function name
and selecting
Pin Function
from the pop-up menu. The function will be moved to the top of the list and
will be highlighted in red to indicate it is pinned. It can be unpinned by left clicking and then selecting
the
Unpin Function
menu option.

or

menu option. There
are short-cuts to search backwards or forwards by clicking on the function name while holding the Ctrl
or Shift key respectively.
