History.
When Silicon Valley was being reclaimed in California, Douglas Engelbart, a researcher of Stanford institute, put on his thinking cap while looking at a computer.
'Can we use a computer more conveniently?'
In those days, using a computer was very inconvenient because of its large size. Having studied for a long time, he succeeded in inventing an input device called 'XY index' at last. Originally it needed two hands to use, but it was developed gradually to be used by one hand. This is the mouse that we commonly use today.
It was used in earnest when the 'Macintosh' of Apple Inc. came out in 1984. And 'Windows' was being used widely as a OS (operating system) of a computer, so the mouse spread rapidly. Now it is fitted in 86% of all computers, and there are about 3 hundred million.

On most computers, the user can move the mouse to move the cursor in the same direction.

The right mouse button is used to open menus that are different depending on where the cursor is. The other mouse buttons can do different things, depending on what software is
