How can I type rough breathing marks in Classical Greek using the Windows 11 Greek Polytonic keyboard?

Question

I'm learning to use the Greek Polytonic keyboard in Windows 11 to type Classical Greek.

I can successfully type the following characters (using α as an example): ᾶ, ἀ, ἄ, ἂ, ά, ά, ἆ, ᾱ. For example, ἄ is produced by typing '/' + 'a' on my keyboard.

However, after spending about half an hour trying all of the key combinations I can think of and looking up shortcuts, I can't type rough breathing marks (i.e. Unicode U+0314 'Combining reversed comma above', see here). Examples of characters that I think should be possible to type are these: ἵ, ἥ, ῥ. From a look online, it seems like '"' + 'a' (for example) should do this, but this just results in a normal alpha for me.

The results are exactly the same for me using the fonts Calibri, Palatino Linotype and Gentium Plus.

Unfortunately, the on-screen keyboard doesn't help: the indicated keys very clearly don't correspond to the actual keyboard combinations required on my keyboard for the characters that I can type.

I would be grateful if anyone is able to indicate where the problem might lie.

Answer 1

This link shows the right keyboard layout, and helpfully shows how to type each diacritic using the deadkeys.

The rough breathings are typed using SHIFT + ' + letter.

Answer 2

This image helps me a lot with this kind of difficulty [1]: https://i.sstatic.net/itMwP8Uj.png. The translation of the portuguese text is this:

• type the accent button and then the desired letter;
• use shift and SIMULTANEOUSLY the accent button. Finally, type the desired letter;
• use AltGr and the accent button simultaneously. Finally, type the desired letter;
• use AltGr, shift and the accent button simultaneously. Finally type the desired letter.

In your case, you should press shift and simultaneously the indicated button. Then, type the character you want (ἁ,ἡ,ὡ,ῥ).

I use Windows 11 as well, so I think it should probably be useful to you.
