Since the title of a link (not the URL) is the part which, in Preview mode, is (visible and) clickable, it stands to reason that the same part should also be clickable* in Edit mode.
Ctrl+Shift+click, and/or whatever other shortcuts may be available in the future.
(This feature request applies to links in the standard Markdown format,
[title](URL), or less commonly,
[title](internal location). Links in the double-bracket Obsidian/wiki-style,
[[Page Name|link title]], are already fully clickable in Edit mode.)
