RE: Strange Characters in Note Windows
I get that too, for example I can make these with CTRL+ various keys:
So long as GP has not been programmed with a hot key for that combination, then it will insert the ASCII character code according to the following chart below, something harking back to the early days of computing and dot matrix printers...
For example CTRL+P will cause print dialog to launch as it is a mapped key, but CTRL+L will cause a Form Feed character (0C) to be inserted into the edit window. As these can not be displayed, they just show as strange characters. If you also add SHIFT it seems to allow the entering of the character even if it is mapped to something else.
