A keyboard support system includes a tool-less, adjustable, in-board clamping apparatus for clamping a track to a base. The clamping apparatus includes clamps each having a clamp top slidable relative to and releasably engageable with a clamp bottom to clamp the track and the base therebetween. A clamp knob is adjustable to tighten and secure the clamp top and clamp bottom together. A positioning apparatus includes a slide coupled to the track for horizontal adjustment. The slide is connected to a shuttle which is coupled to an height adjustment arm for vertical height adjustment by an indexing rod. A keyboard tray for holding a keyboard is connected to a tray support which is coupled to the height adjustment arm for pitch adjustment by a guide rod. A clenching mechanism couples the movements of the indexing rod and guide rod and exerts a biasing force to bias the indexing rod and guide rod at selected height and pitch positions. The biasing force of the clenching mechanism is releasable by pulling on the keyboard tray with one hand for moving the indexing rod and guide rod for substantially simultaneous height and pitch adjustment.
