Description

See https://github.com/rizinorg/cutter/issues/3090 for information.

See the 0x77c5d45a 0f 85 7a ec ff ff jne 0x77c5c0da opcode.

I want to go to the target 0x77c5c0da address, but i can not do it a convenient way - see #3092

So, okay, i want to at list quickly copy it. But it is harder than it needs too.

Text editors and WWW browsers have a convenient feature: double-click selects the whole word, and triple-click selects the whole line por paragraph. Would be helpful here too.

Also, Opera/Presto browser had yet another convenience: after double or triple left-click text selection, the context menu for the selected text was opened immediately, skipping the need for an extra right-click. Sounds trivial, but really convenient it was.

Research direction
Examine the disassembly widget in Cutter's source code, likely in files under src/widgets/DisassemblyWidget.cpp and related headers. The feature requires intercepting mouse clicks and expanding selection on double/triple click. Refer to the existing behavior and the discussion in issue #3090 for context. Since the issue is assigned, check if the assignee has left any comments or a WIP branch. The implementation would involve subclassing QPlainTextEdit or similar and overriding mouseDoubleClickEvent.
