How to Quickly Select Matches in Intelligent Completions

  question, vim

Ctrl n ,ctrl p to move the mouse, is there a faster way to select matching items?

If I need to choose the 6th readimage,
1. ctrl n is too slow to move the mouse, and you cannot enter a value of 6 to select it.

2. Move the mouse to the 6th, press the click key, and cannot choose.
If only you could use the mouse to select.

How do you all do it?

Set mouse=a is useless.

If fuzzy matching is supported, enter the following characters. Ycm supports fuzzy matching
