Most of the work you do creating songs in LMMS will be done in the program's windowed GUI. Each type of window has a specific purpose.

## Parameters

LMMS has many types of common parameters. Most parameters have a similar type of right-click context menu with some common options.

Most of the parameters in LMMS can be automated by dragging with Ctrl-drag. There are some more convenient shortcuts that can be used without the hassle of navigating through a right-click menu.

* Double-click a parameter to edit its value
* Middle-mouse click on a parameter to reset its value
* Shift-drag one knob onto another to copy the value of the first knob to the second
* Ctrl-scroll on a knob for more fine scrolling (minute changes, slower scroll)
* Shift-scroll on a knob for more coarse scrolling (larger changes, faster scroll)
