Most of lmms controls -all knobs and almost all sliders will move in a single-value-step if you scroll your mouse-wheel:
Just rest the cursor over the knob, and then scroll your mouse-wheel.
There is even a readout of the new value.
No 'largeMove' exists, but rightclic a knob -the context-menu opens, and you and type the new value in
-----
uhoh forgot - the mousewheel trick is also good fot getting rid of the pesty bug that sometimes apear, do to the implementation of the 'sticky-knob-feature'. This implementation is flawed and will sometimes freeze a knob in a fixed position. If you scroll a new value in, the freeze is gone and you and now turn the knob freely again
