Geoff did a really nice job of listing out browser specific shortcuts keys that one should take into consideration when assigning accesskeys to elements.
Reserved Keys in IE 5.5/6
- F – File
- E – Edit
- V – View
- A – Favorites
- T – Tools
- D – Address
- H – Help
Reserved Keys in NS 7
- F – File
- E – Edit
- V – View
- G – Go
- B – Bookmarks
- T – Tools
- H – Help
- W – Window
Reserved Keys in Opera 7
- F – File
- E – Edit
- V – View
- N – Navigate
- B – Bookmark
- M – Mail
- W – Window
- H – Help
Thus the remaining available accesskey values are (at most):
`, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, -, =, [, ], /, C, I, J, K, L, O, P, Q, R, S, U, X, Y, Z
