switching tabs without closing fzf

[DZ84]

• [x] I have fzf 0.30.0 or above
• [x] I have read through https://github.com/junegunn/fzf.vim/blob/master/README.md
• [x] I have read through https://github.com/junegunn/fzf/blob/master/README-VIM.md
• [x] I have read through the manual page of fzf (man fzf)
• [x] I have searched through the existing issues

This is a question not really an issue.

I see in this(https://github.com/junegunn/fzf.vim/issues/192) old post that fzf cannot communicate with vim, is this still the case?

I would like to switch between tabs via ctrl+J/ctrl+K without closing fzf, so I would like to override/add certain keymappings. I know it's possible with mouse clicks, but obviously I would prefer using the keyboard.
