![]() For example, if you placed the cursor somewhere, then held Paste and went off to select some text, that would become the secondary selection – releasing Paste would immediately paste the selected text at the cursor location. In SunView, the secondary selection worked a bit like primary selection, but it was invoked by holding one of the function keys. However, instead of using combination hotkeys like Ctrl+V, Sun keyboards had dedicated physical keys for Cut, Copy and Paste on the left side of the keyboard. SunView had selections very similar to the ones in X11 – it had Primary, Secondary, and Shelf (which was the SunView name for the clipboard). The secondary selection is a relic that nothing in X11 uses anymore, but most likely it comes from the SunView graphical environment that predated X and was exclusive to Sun workstations. (In other programs, the behavior of Shift+Ins varies – it could paste from clipboard, from primary, or even from a cutbuffer.) Secondary In terminal apps, Shift Ins usually pastes from primary selection, while Ctrl Shift V pastes from the clipboard. So while in Windows you can highlight some text in window A without losing the previous highlight in window B, you can't do that in X11.) (Because the primary selection is meant to directly reflect currently highlighted text, most X11 apps will actually remove the highlight when something else is put into primary. For mice or touchpads with only two buttons, pressing both at once emulates the middle button.) There is neither a menu item nor a standard keyboard shortcut for pasting from primary. (For mice with a scroll wheel, the wheel is also the middle button. You paste from primary selection by middle-clicking the mouse. (Normally the primary selection is only used for text, not images or other data types.) In contrast, the primary selection will automatically hold whatever text you have selected last. If they behave differently, I would call that a Gedit bug.) (The right-click menu should have operations identical to the Edit menu, both accessing the same clipboard. ![]() In other words, it's literally your standard clipboard. ![]() You copy data into the 'CLIPBOARD' selection using Ctrl C or "Edit>Copy" and paste from it with Ctrl+V or "Edit>Paste". The clipboard selection is used for explicit "Cut", "Copy", and "Paste" operations, exactly like in other systems. Cut buffers are not selections they're a different and obsolete mechanism) Clipboard & Primary (Primary and secondary are the other two selections. ![]() "Ĭircle i,(rnd*500,rnd*500),10+rnd*50,rgba(rnd*255,rnd*255,rnd*255,100+rnd*155),fĭim As String path="Circles.In X11 terminology, there are many selections, but only one of them is called the clipboard.

This is OK because for GNU, my plan is to only use this little project myself, but I'm going to share it with Windows users, so I would like to avoid dependencies for them. I've solved the GNU/Linux part by just calling the "xclip" external command for now. In this case, it should be just about five lines of code to push a string to the clipboard and the same again for reading it. In the end, this results in nobody really knowing how things work and possibly thousands of projects having a bug because it's in the library. but it really is a shame that people have gotten used to immediately rely on third-party software as soon as a difficulty comes up. ![]()
