Mode: force_next
Version: 56.0.2894.0
Reproduction Steps: 
1. Launch Chromevox Next
2. sheets.google.com>>open a workbook with multiple sheets.
3. Attempt to switch between sheets using the keyboard shortcut outlined in help (Alt+Shift+K)
Expected: This, or *any* hotkey will switch to, or list the sheets in the workbook.
Actual: This hotkey does not work, and I am not familiar with any other hotkey short of getting out of editing mode, navigating to the bottom of the page, and moving up to find the sheet. This is a productivity issue.
