This is not CAD specific but is still worth mentioning.  Sometimes when you try to refer to a long link URL in an email or news post, the link can become broken because the mail/news tool wraps the link into two (or more) lines.  Unknowing users are frustrated because the link doesn’t appear to work when they click it, and even experienced users have to paste it into a notepad and remove the line breaks.

In this situation, head to and paste in your long link.  A tinyurl ‘mapped’ link will be returned thats usually 20-30 characters and will never break.

Sometimes settings (such as FILEDIA) can cause certain routines to ask for a file name at the command prompt.  In these cases you can enter the tilde ~ character followed by enter to bring up the file selection dialog.

When you press F2 and look back at the command history, you may notice that at some point it stops. The default number of lines is set to 400.  On early versions of AutoCAD you could change it in the preferences dialog. Unfortunately 2000 and higher has regressed. You have to use a to lisp expression setting.
