I find it more time consuming to go through a bunch of menus and GUI windows to find something I'm trying to do vs being able to just run a command or Google for a command and run that instead.
Plus, for common actions with annoying to type syntax you can make a custom key bind (Vim) or alias (Bash). Then it becomes extremely easy to do once you memorize a single key bind.
Have you ever even used a modern IDE?
I don't think I've actually clicked on a menu item in IntelliJ like, ever. Not once.
I just press "shift shift" and get the the "search everywhere" dialog which searches everything including menus and customization preferences.
Yes, I used PyCharm and RubyMine for over a year. The comment I was replying to said he was clicking around menu items to see what's available.
I don't really see a difference between using "search everywhere" vs using something like fzf with Vim (which lets you search through a ton of different things besides files).
But normally in my day to day I'm just hitting key binds or typing short commands without having to search for anything except files to open (which I could do with a sidebar instead, but I prefer fuzzy finding files based on typing out the name most of the time).
Vim's help command is also world class. It's just searching it is hard, but fzf.vim makes this easy, so you can literally type 1 word of what you want to learn more about and you'll find all sorts of results.
