I was walking around a large list of files in the Find dialog. At some stage, I selected a large block of files. Then I pressed F3 to view the 'focused' (lastly selected, with a rectangle around it) file. I also could use F4 to edit it, or Space to focus it. This all works very well, and as documented.
However, I also wanted to Open the file, so I pressed Enter. That was a bad idea: Salamander then tried to open
all selected files!

Thanks to PSKILL I could easily close tens of processes at once easily.
Maybe Salamander should warn against opening too many files at once?
In the help file, I found:
Open (the Enter key): open the focused file or directory,
I think this should read "open the selected files or directories" instead!
