Remarks
This class provides a set of scrolling UI actions for GcMultiRow, such as

You can register an action to a specific key by using the ShortcutKeyManager.Register method of the GcMultiRow.ShortcutKeyManager property. You can call an action's IAction.Execute method directly to execute an action.

Example
The following code example shows how to manage GcMultiRow controls shortcut key settings. The example shows how to change a key's action, and how to customize your own action. This code example is part of a larger example provided for the GcMultiRow.ShortcutKeyManager property.
void Form1_Load(object sender, EventArgs e)
        {
            gcMultiRow1.Template = Template.Default;
            gcMultiRow1.RowCount = 5;

            // Register another action to an existing key. Unregister old key first.
            this.gcMultiRow1.ShortcutKeyManager.Unregister(Keys.Enter);
            // Register to new action.
            this.gcMultiRow1.ShortcutKeyManager.Register(new EditThenMoveNextAction(), Keys.Enter);

            // Register an action list. Select all first, and then, copy.
            this.gcMultiRow1.ShortcutKeyManager.Register(new ActionList(SelectionActions.SelectAll, EditingActions.Copy), Keys.Control | Keys.Shift | Keys.C);
        }

        class EditThenMoveNextAction : Action
        {
            public override bool CanExecute(GcMultiRow target)
