I'd also suggest "home row modifier keys" (or "home row mods").
The idea is to have the key behave the same when tapped, but differently if held. (e.g. https://github.com/evilC/TapHoldManager implements this for AHK)
With home row modifiers, Shift/Ctrl/Win/Alt are put underneath fdsa (and jkl;). -- This reduces the need to use pinky fingers for these keys, & the fingers get to remain on home row more.
