I am wondering how many posts in the forum start with "I am new to Opto, but can anyone answer the following question".
While appreciating that nobody these days wants to waste their valuable time reading the excellent product manuals, its probably worth reminding new users that PAC Control, PAC Display (and nearly all other Opto22 software) have an amazing feature called online help. Think of it of being like google search but limited to the software you are actually working with at the time.
Lets take the above example. A perfectly good question about how to use on screen keyboards within PAC Display.
Cursor to Help> Contents and Index
This pulls up the automatic help guide for the associated software package, in this case PAC Display. With the Search Tab active, in this case just type "keyboard setup". In this case three possible subject areas are suggested, the first one being "Runtime Setup Dialog Box".
Just look what appears like magic when you select it.
The online help guide gives details on every single option and feature included in the software, including every configurable field in every available window. You just have to type in a couple of words of what you are looking for and Opto22 does the rest. The exact answer you wanted just by typing two words. Pressing the [Screen] button (or local equivalent!) informs you of the relevant configuration window.
Your only problem now is to think about how to use all that extra free time you have just saved.
In short, I think we should always check first the online help before to avoid posting basic questions to the Opto Forum about system software features that are already completely documented by Opto22
