Home computer use: copy and paste, perhaps with a step in between

Self-tutoring about home computer use: the tutor mentions a trick he uses seldom, yet does count on sometimes.

Moving between applications, it seems one often needs to copy a filename or link from one program into another. Yet, I find that some programs don’t seem to accept a paste directly from a particular other program. On the other hand, the link may simply be too long and complex to remember.

For such cases, I have a text editor always open. I paste the link into the text editor, then copy it from there into the other program, which then accepts it (for some reason). It’s a trick I have to use sometimes.
