Add Strings
A laser string is any information that you want to include in a laser projection file, but it should not be used to control laser projection. Examples include instructions or notes.

| Instructions | Instructions associated with this projection. Instructions require an acknowledgment that they have been read. |
| LED | Pass messages to an LED crawl board; for example, ply name or material |
| Notes | Free-form text to include with the laser file. |
| Query | Create "yes" or "no" questions; responses are recorded in reports |
| Graphic | Display graphic on a flat screen while running laser projection |
| Literal | Add comment information to keep with the file, but to be ignored by the laser such as time/date stamp or author information |
