repeat motion with ; and , like default vim

[kvngvikram]

Hi,
I am habituated to use ; and , for repeating last f, t, F, T from the default vim behavior.
I like using the hints, but when i fallback to pressing , or ; nothing works.
Is it possible to just save the letter used for hits so that , and ; can also work later?

Let me give an example, here is a line

function(arg1, arg2, arg3, arg4)

and my cursor is somewhere in between. I want to delete some argument completely. I can use hints from hop.nvim to go the ',' character and then press 'd;' or 'd,' . Here I am trying to use the default ; and , functionality but it doesn't work. Instead of pressing just , or ; I have to press f or t and select the hints which is more keypresses and annoying.

Should I config something ? I was not able to find.
Thanks.

I'm having a very similar problem, that is corresponding to repetition with . for example cT" to change something till ".
When I'm pressing the dot, the keyboard in vim is freezing and I need to ctrl-c to bring it back to life.
