Thanks for suggestions.
However, being able to print the symbol with one keystroke as I could using a macro (instead of Insert, finding the right symbol on the symbol chart, clicking on it, backing to right position in order to mark it, choosing the proper color, moving one step and change back to black for the following text).

So is there anywhere a good instruction to create a macro, choose a keyboard combination allowed or if occupied have that replaced if possible. The guide just says pick a combination that is not taken.....

Are only Ctrl and Alt combinations allowed or is AltGr also allowed.
