### Prefix Area Popup Menu

When you click mouse button 2 [note] in the prefix area of an executable line in a Source window, a popup menu appears with some or all of the following choices:

- Run to location -- run to this line
- Jump to location -- jump to this line
- Set breakpoint -- set a breakpoint at this line
- Set line breakpoint -- open the Line Breakpoint window
- Clear breakpoint -- clear the breakpoint at this line
- Disable breakpoint -- disable the breakpoint at this line
- Enable breakpoint -- enable the disabled breakpoint at this line

Executable lines are shown in blue, while non-executable lines (such as comment lines) are shown in black.
