The functionality is maintained until the Show Errors button is selected a second time, making it inactive. The mode cannot be exited with the Esc key. Any command can be executed when the Show Errors button is active, making it possible to interactively fix the errors without leaving Show Errors mode. Note that in the subwindow, only the current error is highlighted, whereas in other windows, all errors are highlighted, if the errors were generated in the current session, otherwise no errors are shown.
Show Errors mode is terminated if a new cell is opened for editing, including Push and Pop, and upon switching to electrical mode. However, If the command is restarted later with the same cell and error file, the first error shown will be the error visible when the command was terminated.
The PageDown or Ctrl-F keys can be used to access the errors randomly, by number. Entering a number followed by PageDown or Ctrl-F will display the corresponding error. One can also enter + or - ahead of the number, in which case PageDown and Ctrl-F will move backward or forward in the list by the number.
