Tell HN: Vim Has Autocomplete

I've been a vim user since 2014 I think. Sometimes I'd accidentally mash some keys while typing and this beautiful green dropdown menu would momentarily flash before my eyes.

I had no idea what it was but it looked like an autocomplete. Initially I thought it was from the OS, or the terminal emulator. But slowly I began to form the idea that: Could it really be vim...itself?

Vainly I search for the secret command in the past. Google failed me. StackOverflow failed me. My search fu was weak I suppose....but today I am victorious.

I have discovered the secret combination. Thank you ChatGPT for enlightening me.

Crtl-X Crtl-L summons the magical menu.

There's a bunch of other combinations too:

  Ctrl-X Ctrl-F: File name completion
  Ctrl-X Ctrl-K: Dictionary completion
  Ctrl-X Ctrl-T: Thesaurus completion

Finally I can use this useful feature!
