Makes the execution position visible (if there is one). The current source tab is brought to the top, and its execution position line is scrolled to.
While probably not useful as a standalone command, showExecutionPosition can be mapped to a key and/or a client UI button. This can be done in either of two ways:
<mapping command="showExecutionPosition" button="button0" key="F2"/>
mapButton button1 showExecutionPosition
mapKey f3 showExecutionPosition
