Standard software behaviour is
CTRL + C to copy
CTRL + V to paste
CTRL + X to “cut” (copy and delete simultaneously)
In some editors in blender all three of these are implemented (text editor, not sure if others)
In most contexts only Copy and Paste are implemented (outliner, node editor, object mode in viewport)
Worst of all, in some contexts CTRL+X and CTRL+V are used for other things (for example in edit mode these correspond to “dissolve” and “vertex” menus)
Ensure Cut, Copy, AND Paste are implemented across all editors, and all use the same hotkeys.
