The ShortcutKeyAlignH / ShortcutKeyAlignV defines the alignment of the UI shortcut keys relative to the item that displays it, when the holder arranges the items horizontally / vertically. The ShortcutKeyVisible property indicates the way the control shows the available keys when user presses any modifier keys such as SHIFT, CTRL or ALT. The Shortcut property specifies the key combination that the user can press to select the item quickly. The ShortcutKeysInfo property returns the list of shortcut keys that are currently available. 

The following properties customize the format/look the shortcut keys are displayed:

• The ShortcutKeyFormat property specifies the expression that defines the format (including HTML tags) to display the shortcut keys.

• Background(exShortcutKeyAppearance) / Background(exShortcutKeyBackColor) /  Background(exShortcutKeyForeColor)  specifies the visual appearance of the shortcut's background / foreground

• The ShortcutKeyTransparent property Indicates the percent of transparency the shortcut keys are being displayed with.

• The ShortcutKeyPadding property specifies the UI shortcut key's content padding.

• The ShortcutKeyExtPaddingH / ShortcutKeyExtPaddingV specifies the padding to be applied to the item (arranged horizontally/vertically) that displays the UI shortcut, so the ShortcutKeyAlign property aligns the UI shortcut relative to this.

The ShortcutKeyPressedModifers property indicates the combination of modifier keys whose shortcut keys are currently visible.
