Does it depend how the the user executes "scrolling"?

1) Say the user single-clicks on any date, thus loading the display area. With 
this (or any other date) now "in focus", I gather that sequential key-presses 
(or continuously holding down) on up-cursor or down-cursor will cause each date 
to be "in focus" and sequential loading of the display. If this translates into 
noticeable lags where the user did not actually want to see those "results 
along the way", then the user would have to get to the date of interest "some 
other way".

2) "some other way" depends on whether the user can see the date of interest in 
the viewing area … if yes, they simply click directly on it, bypassing to 
activate the dates in between

… but if results exist for more dates than are visible in the user's viewing 
area (especially on a laptop), either a scrollbar thumb or a two-finger 
trackpad "swipe" should allow to change the area, and therefore which dates are 
in view, without having to activate each date. Have I got that right?
