Agenda - Monthly Accessibility Focus

Accessibility Topics

Accessibility Triage / Needs Discussion

• Dan: Search highlights - Colors for search in notebook and jupyterlab are difficult to use and may be inaccessible jupyter/notebook#7644
  • Team agrees current highlighting colors (yellow current, black with white text for others) aren't great, however, not sure if there is another search problem here
  • Dan to ask about the problem to clarify, what browser, OS, and what the real problem is
  • Need to investigate if we can use browser default colors

Other Topics

• Dan: Cell execution number references - Need cell execution_number while calling dumpCell jupyterlab#17661
  • This is for the debugger component, which may not currently provide a cell ID.
  • Drawback to using a hash function is two identical cells could have the same hash
  • Recommendation is to add a cell ID, which would technically change the kernel message protocol and would require a JEP
  • First create an experimental PR
• Mike: per cell button Per-cell run button jupyterlab#16602
  • Adds a run button on top of the cell number if it hasn't been run
  • Concerns with accessibility and touchscreen manipulation for this hover design
  • CoCalc and Collab have a play button, may need to benchmark what is available
  • Add screenshots to Per cell UI for running cells jupyterlab#2109
• Dan: Gator v6.0.0 is now out

Offline Topics

• None
