Tooltip element names in palettes does not match shortcut names
Hoovering above the lines category in the palettes pane gives a tooltip with the name of the elements, but these names are often different than the list of names used for the shortcuts in Edit > Preferences > Shortcuts.
For instance, in the lines palette, the second and third items are called 'crescendo hairpin' and 'diminuendo hairpin'. But searching for the keyword 'hairpin' in the shortcuts menu gives no results because those are called 'Add crescendo' and 'Add diminuendo' in that list. There might be many other inconsistencies other than the hairpins.
