NVDA is a solid tool for testing your web applications are accessible to blind and vision-impaired users. (If you find it useful, you can donate here!)
As a non-vision impaired person, these are the keyboard shortcuts I find most useful for building accessible web applications. I keep NumLock off and use Insert as my NVDA modifier key.
| Shortcut | Purpose |
|---|---|
| Numpad + | Read starting at current position |
| ↓ | Next/down |
| ↑ | Previous/up |
| Tab | Next control |
| Shift + Tab | Previous control |
| NVDA + Tab | Announce control that has focus |
| Shift + , | Start of container (e.g. list, table) |
| , | End of container |
| Spacebar | Check/uncheck |
| Alt + ↓ | Open combo box |
| NVDA + Space | Enter forms mode (to edit text) |
| NVDA + Numpad 7 | Next review mode (object/document/screen) |
| NVDA + Numpad 1 | Previous review mode |
| NVDA + F7 | Elements list |
| NVDA + S | Toggle speech mode |
| NVDA + 1 | Toggle help mode (press a key for info about its NVDA command) |
Last but not least, the handy grid of review commands adapted from the user guide! Imagine your number pad like this…
| Prev | Curr | Next | |
|---|---|---|---|
| Line | 7 | 8 | 9 |
| Word | 4 | 5 | 6 |
| Char | 1 | 2 | 3 |
