To illustrate this, let’s try, for example, the DEM BW ( demodulator filter
bandwidth ) control located above the Demodulator spectrum :
Clicking on the arrow button opens a drop-down menu showing a list of values
to select from, as you would expect. This drop-down will be also displayed if
you simply hover above the button. Spinning the mouse wheel will move the
list up and down with a little bit of inertia; the faster you spin, the faster the
imaginary “wheel” will turn. Clicking on an item will select it;
double clicking will select it and also close the list.
If you don’t have a mouse wheel (for example using a laptop with a touch
pad instead of a mouse), you can also use the keyboard up/down cursor
keys to navigate inside the list.
There is also another difference with this control: On a long list, you can “click
and drag” the list, and the mouse cursor wraps from the top to the bottom of
the screen and vice versa. This does not select the item you clicked on, but
moves the whole list up and down underneath the selection. This works
particularly well with a trackpad on a notebook.
Did you know?
The mouse wheel was invented by Eric Michelman in 1995 for the Genius EasyScroll
mouse made by a Taiwanese company called KYE Systems.
