Ruler on the side

I can't see the calendar icon on the ruler on the side. Does it move and if so how do I make it show the calendar? It would be handy to have some instructions for idiots! Sorry.

Hi Applestrudel,
iDoceo has two different working modes, what we call compact and full-size
I'm not sure if you've switched to full-size already, probably not! , and that is why you can't find that calendar button.
You'll find here some detailed explanation on these modes .

If you are already in full-size mode, tap on Schedule (on the ruler) and then the calendar will appear in the new set of buttons.

If still can't sort it out, do not hesitate to post.

I'm sure I'm being a bit thick but how do I actually switch to the full size mode?

Ah! I've found it now! Thanks. Have worked with special needs for so many years my brain has turned to mush!
