I want to yank multiple lines in a single register in vim, to easily paste different text templates in a document.
For example, "iyy yanks only the the current line, if I try to select multiple lines in visual-mode, it isn't written into the register.
Any suggestions?
Use 3Y to yank 3 lines into the default register; "i3Y for yanking into register i.
Also, my favorite way is not to count the lines I want to yank, but to select them in visual mode via V and moving commands, and then hit y to yank it or "_y to yank into a register.
Also, I have just tried selecting multiple lines in Visual Line mode and yanking into not-default register, e.g. Vjjj"oy — and it works.
From anywhere within the file, you can use the following.
:2,5y a
Yank lines 2 - 5. INTO REGISTER a
:7pu a
Paste register a under line 7.
Use m to mark the start, with a buffer name (so you might type mx). Move your cursor down to where you want to stop copying, and type y'x (or d'x if you're cutting and pasting). Then move the to the point where you want to paste, and type p.
You prefix the command with a number to get how many lines to operate on. You could also use a 'text-object' (like ']' for block, and ')' for paragraph) - this would work on multiple lines contextually - the default is often a single line. For example, "r5yy would yank five lines starting at the cursor into the 'r' register. (Or you could type :.,+4y r to do the same in ex mode.) You can combine numbers with text-objects as well; "r10y).
It's possible to yank multiple lines in case when it is a last search occurrence.
For example given the following a multiline non-greedy pattern:
/start\_.\{-}end/norm gn"iy
then you'll have your yanked multiline pattern (between start and end) in your @i register (print by echo @i).

Somehow we’ve missed that yank is an operator, which means it works on all motions and text-objects (see the relevant help sections).
That means that yip, y), ygg, yib, etc., all work (and with registers, too)! They can potentially be multiple lines.
Note that some motions are not line-wise by default. You can use yV{motion} to force a line-wise yank.
Might be not much related to this question. However, if someone needs to copy all lines into a register do it with %
:%y a
