Currently, to paste value without format in Calc using keyboard is a pain in the *ss because we have to press 4 keys: Ctrl+Shift+Alt+V
Please implement fewer keys like in Google spreadsheet: Ctrl+Shift+V
Or even better: two keys or one key
Two keys: it seems like Ctrl+E, Ctrl+L and Ctrl+T are available
One key: F6
Assign any shortcut you like.
In Calc main menu, Tools -> Customize... dialog. On the 'Keyboard' for 'Calc' module.
You'll want the "Paste Only Numbers" entry ('.uno:PasteOnlyValue'), or if you prefer the "Paste Unformatted Text" entry ('.uno:PasteUnformatted') which as noted is assigned the shortcut <Ctrl>+<Shift>+<Alt>+V.
As can be infinitely customized by user--no valid requirement to change what are reasonable UI defaults.
