This is an umbrella issue to address several usability issues we currently have with adding comments, selecting source code and scrolling the page.

Problems reported by users:

• selecting source code opens the "Add comment" inline dialog; instead of this it should allow to copy code, also from multiple lines (CRUC-1218, CRUC-5890, CRUC-7294*, CRUC-7751)
• current "Alt+drag mouse" for code selection does not work on some Linux distributions (CRUC-5919)
• it should be possible to set the code viewport as active for scrolling purposes (CRUC-6332)

What we need

• selection of source code using a mouse without a need to hold Alt (or any other key)
• selection of multiple source code lines should select code only and not line numbers
• adding new comments
• adding new comments covering multiple source lines (also non-continuous ones)
• single click on source code should do nothing (i.e. just set a focus for scrolling)

How it could work (proposal)

• hovering mouse over left margin with line numbers would show the "<+>" button
  • clicking on it would show the "Add comment" dialog
  • pressing Ctrl/Cmd should allow to mark additional lines
• selecting source lines using a mouse would select source code
  • it would not pop-up the "Add comment" dialog
  • it would not select row numbers
• a single click on the source code would do nothing
  • it's to give a focus on the frame for scrolling

Workaround

A bug fix for copying source is available as a Copy Source for FishEye and Crucible plugin on Marketplace.
