Description

What is the feature you'd like to have?
Add a command that allows the user to enter an Objective-C selector, matches it against known selectors in the binary, and jumps to the implementation of that selector. If more than one class implements the selector, the user should be able to select which implementation to jump to.

Workaround:

Search for sel_<selectorName> in the symbols list, navigate to it, then navigate to the implementation via the cross references pane.

Additional Information:
Requested by a user on public Slack.

Research direction

Start by tracing the existing command and symbols-list workflow described in the workaround, including navigation through cross references. Determine how known Objective-C selectors and their implementations are exposed, then define the selection behavior for selectors implemented by multiple classes. Done means a user can enter a selector by name, choose among matching implementations when needed, and jump directly to the selected implementation.
