Used in vim insertion mode
Ctrl-Shift-vWhen pasting the contents of the system clipboard, the speed is extremely slow. Sometimes a paragraph of text is pasted in several sentences. If the pasted contents are too much, it may even get stuck. In the normal mode, there is almost no delay in pasting the same amount of content with “+p”. Why is this?
Ctrl-Shift-v is equivalent to analog input. Each character is treated as a key, which will trigger any logic that may be triggered, including highlighting, indenting bracket matching, word wrapping, etc. The speed is necessarily slow.
“+p is to insert the value from the register into buf at one time, so it is fast.
