Can't edit end of Automation Track

Having trouble with LMMS? Ask about it here.
Using LMMS on Win10. When I try and edit an Automation Track, I can't scroll to the end of the song in the Automation Editor. The first bar stays firmly stuck to the LH end of the window.
Does anyone know the Magic Runes needed to scroll to the Right please?

On LMMS 1.1.3

If you place an automation block, for example, at the beginning of the track, at measure 1, and you want to automate something that is for example at measure 140, you can do it gradually, with the mouse: open the automation editor, place a value as far as you can, it will allow you to access the measures that are later in the timeline. Do this as many times as necessary until you reach the measurement that interests you.

This way is not very practical.

The best is to place an automation block in the right place (at measure 140 if that's where you want to do your automation).

You can also record your automation:
- place the loop playback markers where you want to do your automation,
- place the automation block at this measure,
- right-click on your automation block and choose Set / Clear recording (red circle symbol)
- presses on play to start the playback
- and modify the values you want to automate, LMMS record it.

Does this answer the problem you have?
Thanks D.Ipsum, Just putting the Automation Block at the end bars worked fine.
I'll try the recording method too when I have a large section to Automate.
Thanks again
