Your idea

Have an "add text: dynamics" command that can have a keyboard shortcut assigned (Ctrl+D is available in the default map) that parses the dynamic at the end of editing to set the playback.

Problem to be solved

The only way to enter a dynamic from the keyboard is through the accessibility interface. Being a general interface, this takes much longer than a dedicated shortcut could. Rather than taking up extra shortcuts for each separate dynamic, a simple way to start editing a text object with the dynamic type would be economical and quick.

Prior art

Sibelius includes dynamics in its expression text, and uses a playback dictionary to find words that should affect playback, which makes it very powerful, and quick to use. They also have a right-click menu while editing text to add quick snippets appropriate to the type of text being entered.
