I am astonished to discover that this “bug report” has been languishing here unaddressed for three years and two months. So despite...
• the very valid comments about the crippled usability of Sticky Keys without a modifier key status indicator, from multiple end users (which I fully endorse – there are times when only logging out and logging in again will rectify an unknown and non-viable modifier key latched/locked combination);
• “First-class accessibility for those with special interaction needs” being a publicly stated aim for Ubuntu 12.04 LTS Precise Pangolin since at least 2011-10-20; [1]
• SIX missed opportunities to address this critical accessibility problem between Ubuntu 11.10 Oneiric Ocelot and Ubuntu 14.04 LTS Trusty Tahr
...it seems that Canonical either have a worse than useless bug-tracking system (less likely) or assign the needs of people with disabilities a rock bottom priority (more likely, but depressingly disappointing).

I've been using Sticky Keys on Apple Mac OS X for a decade, and occasionally on Micro$oft Windoze, and on both OS's the modifier key status indicators are a crucial component in making Sticky Keys work for unidextrous typing and computer control. The OS X technique of 'sound on modifier key-press' plus 'user-positionable translucent modifier key icon overlays' to show the current latched/locked modifier key combination is far more user friendly than the tiny panel icon in Windoze. Yet a 'one icon per modifier key' panel applet for Ubuntu, integrated into the System Settings > Universal Access > Typing > Sticky Keys, ought to be relatively easy to implement; indeed one end user has coded a 'one icon per modifier key' panel applet, and although it doesn't work on the Gnome Flashback environment I'm using, it does show what's needed:

As an Ubuntu noob, I'm unfamiliar with how best to get Canonical's attention drawn to fixing this problem. If more experienced Ubuntu community members can suggest ways in which to get this long-overdue error corrected, those of us who need a fully functional Sticky Keys implementation would be most grateful.
