Scrolling
|
|
=========
|
|
:Date: 2008-05-07

|
|
This is a draft describing how scrolling with the mouse wheel should work in Lumiera to provide the best possible comfort for long editing sessions.
|
|
|
|
|
|
Scrolling without modifiers
|
|
---------------------------
|
|
|
|
Scrolling without modifiers should jump directly from the current frame to the next/previous frame.
|
|
|
|
|
|
Shift Modifiers
|
|
---------------
|
|
|
|
The Shift modifier should be used to toggle how scrolling with the mouse affects the gui.
|
|
|
|
So scrolling while holding down Shift should not scroll horizontally but instead let you scroll through the tracks vertically. This is just a very small detail, but it does matter if you want to cut 2 hours of a Musical filmed with several cameras and two or more effects-tracks. Then you will mind whether you have to use your mouse at a border of the timeline or if you can let it stay where it is.
|
|
|
|
|
|
Alt Modifier
|
|
------------
|
|
|
|
The Alt modifier should be used to toggle the degree to which scrolling with the mouse affects the gui.
|
|
|
|
If you want to scroll a bit through the video by scrolling, you might not want to see every single frame, but you would be satisfied if you see only every 10th.
|
|
|
|
|
|
Windows / Tux / Super Modifier
|
|
------------------------------
|
|
|
|
The Windows / Tux / Super Modifier should give you a special feature often called a shuttle.
|
|
|
|
Hold down Super and scroll a bit up or down to get a very slow but steady forward / backward play like a extreme slow motion but with changing speed.
|
|
|
|
(I use the Super/Meta 4 key exclusively for window manager-related operations, as is increasingly common. If we use it in the application, at least let it be unmapped so we don't clobber people's bindings. --rcb)
|
|
|
|
|
|
Ctrl Modifier
|
|
-------------
|
|
|
|
The Ctrl modifier should switch from normal scrolling to zooming like in most other applications.
|
|
|
|
Here again the Shift modifier held down together with the Control modifier should switch from time-zoom to switching the height of a track.
|
|
|
|
But in the second case there is a need for another definition: As every track can have it's own height, there should also be the possibility of changing the height of all tracks at one time. Here it would be a good idea to let the modifier change its catchment area to all tracks when the mouse pointer is over a trackhead as this should be a big enough area so that you don't have to care on which pixel the mouse pointer exactly is.
