To make my life easier, I have defined the following two commands:


However, as you can see, the latter one required a redefinition, rather than a new definition. I tried to look for its definition, but it's not listed among other special escaped characters in various lists online (among these: # $ % & ~ _ ^ \ { }). Plus, the command itself doesn't actually print anything when I use it.

I work in Overleaf. Will something bad happen if I redefine it like this?
