more detail would be helpful but a few things off the top of my head given what you do say --

check the TRASH icon. you said something JUMPED off the tool bar. It may be in trash and you can drag it back

What application is it written in? PAGES? DId you look directly in that application?

You should be able to find them in FINDER/DOCUMENTS if they are not in trash

Last add do you have a backup to your system? Hope so
