When you click the Run Macro Now it doesn't ask you which window to type in. Since the first line is a Text Type command Macro Express is typing into it's own window. The text is typed into the window that has focus.
The log entry "Tuesday, November 21, 2023 11:18:18:668 AM: TMainWin.tmrFixFirstLineTimer: An error in the first line of the script has been fixed" happens when there was a problem displaying the first line of a macro in the Script Editor. It has no effect on the macro running.
Log entries that include MacScript are events that occur in the Script Editor. Entries that include MacEdit are events that occur in the Macro Express Explorer. For events that occur in the Player look for log entries that include MacExp.
Here are some things to try:
1. Press and release the Ctrl key and then type the shortkey activation again.
2. Make sure you are typing the correct characters to activate the shortkey. Highlight the shortkey macro in the Macro Express Explorer window. In the yellow box under the list of macros the keys needed to activate the shortkey are displayed. For example, it may show something like Shortkey //ps
To activate the shortkey macro type all the keystrokes shown.
3. You can adjust what is needed to activate shortkeys in the Activations, Shortkeys preferences. Depending on those settings you may need to press space before or after the shortkey characters.
4. To see if the macro is activating put something at the top of your macro like a Text Box Display. You could also have Macro Express play a sound when a macro is activated. This is found in the Playback, Miscellaneous preferences. But it is annoying to have a sound played every time a macro is activated so you will probably want to turn this off after your test.
