Is it RSView32?
If so, go to the keyboard and press CTRL+ALP+P, P, if i remember correctly.
That will bring up the run edit dialog where you can switch to edit mode from run mode. I think this requires that a RSView32 Works license exists or can be validated from that PC. It is also possible to lock out that key combination. The Windows Start key can be enabled or disabled as well, but on a touchscreen system, we leave it available, and keep the keyboard in the panel for engineer access only.
Once you get into edit mode, I like to turn on the grid as a reminder, and then you should be able to double click your way into any object on the screen. Take note of the mouse pointer symbol. IIRC, in their editor, you have to make sure you have the arrow mouse pointer at times before you can drill into objects.
Once inside the object properties, there may be multiple tabs and some may have check marks on them for different actions and behaviors, like animation, color and visibility. The contents of those checked tabs is usually a tag, or an expression containing tags which you can browse to, or alternately, open the tag database folder on the left of the run/program mode panes.
