Emacs series tutorial (7): clipboard

Emacs differs slightly in different operating systems. Here I will compare the clipboard of Emacs in different operating systems with the paste copy mentioned in the previous chapter.

 

1. Copy to clipboard

In Emacs, in addition to commands, you can also use shortcut buttons on the toolbar or menu items in the menu bar to cut and copy texts, by default, when you use the toolbar and menu bar for cutting and copying, the relevant content will be sent to the system clipboard for otherProgram. Using C-W or M-W in Windows and Mac OS X also copies the content to the clipboard, but not in Linux.

Another way to select a region is to use the mouse, which also has a small difference, as shown in the following table:

Use the mouse to select a region
	Linux	Windows	Mac OS X
Sent to system clipboard	No	Yes	Yes
Send to kill ring?	Yes	Yes	Yes

In Linux, you can also use several clipboard commands, suchClipboard-kill-regionCut the area and send it to the system clipboard and kill ring,Clipboard-kill-ring-saveCopy the area content to the system clipboard and kill ring. Of course, these two commands can also be used in Windows and Mac. Essentially, these two commands are cut and copy corresponding to the menu bar.

 

2. Extract from clipboard

Since there are differences between the Emacs and the system clipboard, there are also some differences between the clipboard and the Emacs. See the following table:

Paste from system clipboard
	Linux	Windows	Max OS X
C-y Paste	Yes	Yes	Yes
Toolbar paste button	Yes	Yes	No
Paste menu items in the menu bar	Yes	Yes	No
Middle mouse	Yes	Yes	Yes
M-x clipboard-Yank	Yes	Yes	Yes

Here are some explanations. One is the middle mouse button. Some do not have the middle mouse button or the pulley. It also has the paste function, while the commandClipboard-YankPaste the clipboard with the paste function on the menu bar.

 

Summary:

This chapter has very little content, which is a simple comparison. In the future, we will be able to see more Emacs differences on different platforms.

 

Buttons	Command	Function
	Clipboard-kill-region	Cut the area and send it to the system clipboard and kill Ring
	Clipboard-kill-ring-save	Copy the region content to the system clipboard and kill ring.
	Clipboard-Yank	Paste from clipboard to Emacs
