Editing Sequences Using the Keyboard
|Top Previous Next|
Please also see Editing Sequences Using the Mouse.
Although Light-O-Rama has certain built-in keyboard behaviors -- for example, pushing the S key will cause a shimmer to be applied to the current selection -- you can change these behaviors. For example, you could change the S key so that it will cause a fade up to be applied, instead of a shimmer. Or, you could make it more complex, such as causing a shimmer to be applied, then the selection to be moved two cells to the right, and then a fade up applied (to the new selection).
For further details on custom keyboard mappings, please see the Keyboard Preferences page. The remainder of this help file page describes Light-O-Rama's built-in keyboard behaviors.
Sequences are displayed in the Sequence Editor as a grid. Rows represent channels or RGB channels, and columns represent timings. Cells in the grid therefore represent the lighting effects that will happen on channels at various points in time while the sequence is being played.
A cell, or a range of cells, can be selected, allowing you to apply various tools to it (such as specifying what lighting effects should take place in that cell). You can recognize the currently selected cell (or cells) by a thick black and white border. For example, in the following sequence, the cell of the third channel between 1 second and 1.5 seconds is selected:
The time between 1 and 1.5 seconds of the third channel is selected
You can change which cell is selected by using the arrow keys - Up, Down, Left and Right. Page Up and Page Down can also be used, to go up and down in the sequence by a page at a time.
If the currently selected cell is not the first cell in the currently selected channel (i.e. the cell starting at time zero), hitting the Home key brings you to the first cell in the currently selected channel. If, however, the first cell is already selected, then hitting the Home key will bring you to the first channel in the sequence. So, hitting the Home key twice in a row will bring you to the first cell in the first channel.
The End key works similarly, but for the last event and the last channel.
A range of cells can be selected by holding down the shift key while using the arrow keys (or Page Up, Page Down, Home, or End). For example, the following picture has four cells selected, two each from second and third channels:
Four cells are currently selected, two each in Channel 2 and Channel 3
Once you have selected a cell, or a range of cells, you can modify the cell or cells by pressing keys:
The selected cells have been changed to twinkles
The lighting effects in cells can be copied, cut, and pasted using the standard Windows copy, cut and paste keys, Ctrl-C, Ctrl-X, and Ctrl-V.
Note that the Light-O-Rama Sequence Editor supports two different pasting modes (paste by cell and paste by time), and a pasting option (paste from foreground). You can choose these settings using the Clipboards subpanel of the left-hand Tools Panel.
Timings can be copied using Ctrl-Insert, and inserted using Shift-Insert.
Changes to a sequence can be undone and redone using the standard Windows undo and redo keys, Ctrl-Z and Ctrl-Y. Note that this includes any changes to the sequence, not merely changes made using the keyboard.
To zoom in on channels - i.e. to make them bigger - use Alt-Down, and to zoom out, use Alt-Up. Alt-Page Down and Alt-Page Up also work, to zoom in and out as much as possible.
To zoom in on timings, use Alt-Right; to zoom out, use Alt-Left. Alt-End and Alt-Home zoom in and out as much as possible.
The New and Open Dialog can be opened using either Ctrl-N, Ctrl-O, or Ctrl-R. Ctrl-N will open it to its New Sequence tab, Ctrl-O will open it to its Existing Sequence tab, and Ctrl-R will open it to its Recent Sequence tab.
Changes to a sequence can be saved using Ctrl-S. If this is a new sequence that has never before been saved, this will first prompt you for a filename to save the sequence to.
Occasionally during play, the display of a sequence's grid may seem to blank out. This is typically caused when your computer happens to do something unrelated to Light-O-Rama, and temporarily takes the focus away from the Sequence Editor. The sequence itself is not affected, nor are the actual lights - only the Sequence Editor's display of the sequence is - and the display is typically returned to normal when play reaches the next screen (or stops). However, if you do not wish to wait for that, you can hit the F5 key to manually refresh the display.
The Light-O-Rama help file can be opened by hitting the F1 key.
The space bar can be used to start and stop the current sequence either in "from selection" mode or, if a freeform play range has been selected, in freeform play mode. While playing, the up and down arrows can be used to define a freeform play range. If play is started with "Shift-Space" instead of just "Space", the freeform play range will be removed, and play will then start in "from selection" mode.
If your mouse is over the current sequence's grid, you can open a tooltip describing the cell it is pointing to by hitting the "P" key. This can be done regardless of whether you have set your display preferences to disable tooltips.
The various menus on the menu bar can be accessed by holding down the Alt key while pressing a particular key for the menu in question:
After opening a menu, menu items can be selected using their hotkeys (indicated by an underlined letter). For example, pressing Alt-E followed by K will select "Duplicate Track" from the Edit menu. Keys such as Up, Down, Left, Right, Enter and Space can also be used to navigate these menus.
Many functions in the Light-O-Rama Sequence Editor cause dialog windows to open up. Those which have "OK" and "Cancel" buttons can typically have "OK" invoked by hitting the Enter key, and "Cancel" by hitting the Escape key.
Standard Windows keyboard navigation should work on these dialogs - for example, using the Tab key to tab between controls, or the arrow keys to choose which radio button in a group is selected.
Hotkeys exist on many of these dialogs, which allow you to select a specific control on the dialog by holding the Alt key and pressing the key of the underlined letter. For example, in the Channel Settings dialog (picture follows), the "Name" control can be selected by Alt-N, the "Color" control by Alt-C, and so forth:
