A few years ago I posted this tip and someone wanted to know again, so here it is. Most InterForm400 users are using Swiftview a lot to preview the merged PCL result. Most (including me) are using the mouse to close Swiftview when needed, but you can even also close Swiftview simply by pressing F12, by adding this line in the sview.ini file:

ICS0=gui key "F12" quit

The location of the sview.ini file can vary, so the best suggestion is simply to search for it. In my Windows 7 PC it is located here:

C:\Users\<MyUser>\AppData\Local\VirtualStore\Windows\

Open the file in NotePad and add the line above and you are done.

(Yes, I am running Windows 7 and I long back for the good old XP days, when I knew what was up and down of a PC and where to find and change stuff....)
