JLCooper MCS5 - Manual (Page 41)

Display Text Tab
If you check the Display Custom Text box or type into the text boxes below it and hit the ENTER key, the
text you type will be shown on the LCD display line whenever the target application is in front. You can
enter up to 23 characters per line.
Un-checking the Display Custom Text box will delete any function assigned to the currently selected
display line.
As mentioned earlier, if you have reason to display custom text, but sometimes need to see the button
labels, you can assign the Labels function to App Button 8. Whenever you press App Button 8, the button
labels will be shown. Releasing it will cause the display to show the custom text.
