Timeline is a navigation aid that displays at the bottom of the program window, giving you an overview of the instruments and main structural elements measure-by-measure. You can easily move about the score by clicking on a measure or a structural element.
There are four parts to the timeline:
This is found in the top left corner of the timeline. These are the names of the meta rows.
This is found in the bottom left corner of the timeline. These are the names of the rows in the main grid.
This is found in the top right corner of the timeline. These hold the meta values of the score.
This is found in the bottom right corner of the timeline. This holds multiple 'cells' (a specific measure and staff in the score represented as a square)
Meta elements are those found in the score that are not notes, but are still important to the score—such as key signature, time signature, tempo, rehearsal marks, bar lines, and jumps and markers.
To select a measure in the timeline, press the mouse button on the cell. A blue box will appear around the selected cell and the respective measure in the score will be selected. The score view will place the selected measure in view.
Holding Shift and holding the left mouse button and dragging the mouse over the main grid will create a selection box. Upon releasing the mouse button, all the cells underneath the selection box will be selected, as well as all the measures in the score.
If a cell is already selected, holding Shift and selecting another cell in the timeline will stretch the selection to that new cell, similar to how the score does
If no cells are currently selected, holding Ctrl and selecting a cell will select the entire measure
To clear selection, holding Ctrl and clicking anywhere on the grid or the meta rows will clear any current selection.
Selecting the meta values on the timeline will attempt to select the respective meta values in the score.
Scrolling the mouse wheel up or down will move the grid and instrument labels down or up respectively. The meta labels and rows do not move.
Holding Shift and scrolling the mouse wheel up or down will move the grid and meta rows left or right respectively. The meta labels and instrument labels do not move.
Holding Alt and scrolling the mouse wheel up or down will move the grid and meta rows left or right respectively, faster than Shift scrolling. The meta labels and instrument labels do not move.
To drag the contents of the timeline, hold the left mouse button and move it around.
All meta labels besides the measures meta may be rearranged in any way. By moving the mouse cursor onto one of the meta labels, small up and down arrows will appear. Click the left mouse button on the up arrow to swap the meta label with the one above it. Click the left mouse button on the down arrow to swap the meta label with the one below it.
In order to hide all the meta labels while keeping all the meta information on the timeline, click the left mouse button on the measures meta to collapse all the currently visible meta rows into one row, where the meta values are staggered in that row. Click the left mouse button again on the measures meta to expand the meta rows.
All instruments--hidden or not--will be displayed on the timeline. To start this interaction, the mouse cursor is moved over an instrument label. A small eye will appear on the right side of the label that is open if the instrument is visible on the score, and closed if the instrument is hidden. Click the left mouse button on the eye to toggle between the two options.
To zoom in or out of the score, hold Ctrl and scroll the mouse wheel up or down respectively (Mac: Cmd + scroll).
