It is convention in Windows for F2 to rename, but Figma does a kind of literal translation of the macOS cmd+R rename command in Windows.
It’s a small thing, but given that it’s one of many programs in my suite, I am constantly pressing F2 in Figma and being surprised that it does nothing.
I suggest that Figma for windows additionally respects F2.
On a related note: The regex rename dialog when renaming multiple layers is pure genius.
