Better understanding accels/nemo file syntax to add keyboard shortcuts for custom Nemo scripts

I carefully followed the instructions to add keyboard shortcuts to custom Nemo scripts as explained in this Ask Ubuntu answer and this Stack Overflow answer . Although this technique works great to modify Nemo keyboard shortcuts, the instructions aren't working to add keyboard shortcuts to Nemo scripts on a Linux Mint Cinnamon 21.3 box. To help debug this issue, I would like to better understand the syntax of the example line that implements this functionality (this line is contained in the accels/nemo file, which is located in a folder pointed to by environment variable GNOME22_USER_DIR): (gtk_accel_path "/ScriptsGroup/script_file:\\s\\s\\shome\\sUSERNAME\\s.local\\sshare\\snemo\\sscripts\\sedit.sh" "F4") - Why are backslashes used instead of forward slashes? - Why is the use of \s needed? - Just to make sure, is \\s\\s\\s after /script_file: correct? --- *Edit: Shortly after posting this, I resolved the larger issue, but I'm still interested in learning the answers to the above questions.*
