First of all, briefly introduce the key positions of shortcut operation: cutting is ctrl+x copying is ctrl+c pasting is ctrl+v, and the specific key positions are shown in the figure below. It is meaningless to introduce these things with the right mouse button. Here's how to apply them without the right mouse button.
For example, the dialog box of the game does not support direct copy. How to copy a paragraph of text (this method can be used to enter a Chinese name in World of Warcraft LAN) is to enter the text first, then hold down the shift key and use the left and right (←→) direction keys of the keyboard to move in one direction.
At this time, the text in the dialog box is selected and the background color of the text is white.
Press ctrl+c to copy the content. Then it is easy to paste, and Ctrl+V is enough. This method is suitable for some games that are not compatible with Chinese name input.
Copy and paste can also copy the message in the error prompt box. Click the message that pops up in windows to make the message active, and press ctrl+c directly to copy the content. Create a new text document and paste it to see if the message is copied into the text.
The reason why I introduce simple content is because sometimes copying and pasting is impossible for the mouse. At this time, I need to use my brain and keyboard to operate, which may help you solve the problem.
