+### fzf-man-pages widget (for zsh)
+Same functionality as above but better
+- with colored and syntax higlighting 
+- doesn't exit fzf when pressed enter
+- `--tiebreak=begin` for improved search experience (prefers the line with matched substring closer to the beginning)
+- additional keybinds for changing preview (optional)
+  <kbd>Alt-C</kbd> for [cheat sheet](https://github.com/chubin/cheat.sh)
+  <kbd>Alt-T</kbd> for [tldr](https://github.com/tldr-pages/tldr) (I've used [tealdeer](https://github.com/dbrgn/tealdeer) to customize the colors)
+- `Ctrl-H` keybinding to launch the widget (works only on zsh, don't know how to do it on bash and fish (additionaly pressing`ctrl-backspace` will trigger the widget to launch too because both share the same keycode)
