It's even worse than that, there are others, much more likely key combinations that are interpreted by the SSH client. For example "~v" increases the verbosity of the SSH client, "~C" opens a command line, etc.

Entering "~vicky/doc.txt" or "~Ricky/doc.txt" over SSH will actually only write "icky/doc.txt", and entering "~Chris/doc.txt" will have SSH print out it's internal command-line's usage instructions in the middle of the TUI. Screenshot from Vim: https://imgur.com/a/NCt0G9r
