|Proposal pages help us get from feature requests into actual plans. This page is a proposal to reserve a set of special keys/key combinations for a user's custom key bindings.|
Proposal pages are used on an ongoing basis by the Audacity development team and are open to edits from visitors to the wiki. They are a good way to get community feedback on a proposal.
- Note: Proposals for Google Summer of Code projects are significantly different in structure, are submitted via Google's web app and may or may not have a corresponding proposal page.
The documentation (Manual and Wiki) do not offer any advice on key combinations that are available; Audacity cannot easily be used to ascertain sets of available unassigned keystrokes.
Furthermore, any currently unassigned key/key combination that a user chooses to use may subsequently become an Audacity assigned key binding, thus potentially invalidating the user's previous setting and forcing them to search for an alternative key binding. This is definitely sub-optimal as the user is likely to have used their custom binding many times and learnt it well.
Reserve a set of special keys/key combinations for a user's custom key bindings. That would save us a lot of problems and provide users with some easy to find, available key combinations.
Another advantage of having reserved bindings for user's use is that we can document these in the manual for readers.
- One way to ascertain available bindings is to scan Keyboard Shortcut Reference. This is a far from easy and short task.
- Trial and error: an alternative is to just to attempt to bind keys or key combinations in Audacity Edit > Preferences > Keyboard" but this is no easy task either and can also be time consuming.
A number of keystroke combinations between five and nine to be permanently set-aside for user's custom bindings. This number should be sufficient and is based on Miller's Law "The Magical Number Seven Plus or Minus Two" - see: this Wikipedia page.
Ideally a mechanism should be provided within Audacity to lock such keys/key combinations so that future developers cannot assign them as default bindings.
Documentation to be updated on Keyboard Preferences listing the reserved available keys/key combinations.
ALT+UP, ALT+DOWN, ALT+RIGHT, ALT+LEFTI have also recommended the availability of this group to several users on the forum - so I would vote strongly for reserving at least these four.
