sqlplus - CLEAR SCREEN - Oracle SQL Developer shortcut?

Question

With the aim of reducing mouse activity I was wondering if there was such a command shortcut (eg cls or Ctrl + L) to provide the SQL * Plus (?) "CLEAR SCREEN" command functionality found by clicking the rubber-on-end- of-pencil icon in Oracle SQL Developer to clear the lower "Results" sub-tab (... incorrect terminology I'm sure).

Answer 1

To clear the SQL window you can use:

clear screen;

which can also be shortened to

cl scr;
