Lubuntu 18.04.05 LTSを使用しています。
テンキーの5で、マウスの左クリックが出来る機能は、
Lubuntuには搭載されていないのでしょうか？

教えてもらえると助かります。

First, I don’t think you’ll find many speaking Japanese here. That said, I hope you can translate this as easily as I could translate your message (see deepl.com).

This is something that is apparently standard to Ubuntu, but it is not necessarily true with any other flavor, Lubuntu included.

Luckily, there are other solutions, such as the ones found here:

Thank you for your reply.
I tried the usage example using the translation function, but it doesn’t work.
I don’t usually use the ctrl key on the right side, so it would be convenient if I could click with this key.

I wanted to do the same thing as universal accessibility in ZorinOS, but it doesn’t seem easy.
