404 page not found

[Zoran]

Hello,

There are other links in documentation that are broken. Here are some:

Links listed under Reserved Identifiers:
(LEN, SGN, StdCall, TO)

https://zxbasic.readthedocs.io/en/latest...ier/len.md
https://zxbasic.readthedocs.io/en/latest...ier/sgn.md

https://zxbasic.readthedocs.io/en/latest...stdcall.md
https://zxbasic.readthedocs.io/en/latest...fier/to.md -- I don't know whether TO keyword needs a separate page, perhaps it could link to FOR...NEXT. Perhaps there should be a separate page for it after all, as TO is not only used in for loop, but also in substring syntax.


Links under Inbuilt library Functions:
(HEX, INPUT, LCASE, UCASE)

https://zxbasic.readthedocs.io/en/latest...ary/hex.md
https://zxbasic.readthedocs.io/en/latest...y/input.md
https://zxbasic.readthedocs.io/en/latest...g/lcase.md
https://zxbasic.readthedocs.io/en/latest...g/ucase.md

Page Standard libraries contains two links, neither of these works:

keys.bas
strings.bas
(The links for these two seem completely wrong, so I'm not trying to provide these here, just follow the link given above and take a look)
