Hard-coded in asktitle.f, but put here for future editing:

Please enter a brief running title, or hit [Return] to leave the current
value unchanged.  Enter a solitary question mark for help.

Please enter a brief running title, or a solitary question mark for help.

To leave the current value, as indicated in the prompt, unchanged, just hit
[Return].  No change is made on a mere [Return].
 
The text you can enter is limited in length due to program limitations.
Normally, any text you want to enter for a running title is short, but if not,
you will have to very carefully edit file l2htitle.rht, maintaining its layout
unchanged.  In particular, do not split the line.  (Windows Notepad will not
split lines permanently by itself, but be sure to put the filename between
double quotes when you save, or you may save l2htitle.rht.txt instead.)  Then
rerun l2h or makel2h.

To add multiple blank spaces, write each blank space as &nbsp; or they will
be ignored.  The string &nbsp;&nbsp;&nbsp;&nbsp; gives four spaces.

Special characters such as &copy; for the copyright character can be added
from the entities.html list in the subfolder files of the l2hsup folder.
Do not try to add HTML tags: browsers treat titles as plain text.
