How to type in Hebrew characters?
How does one change keyboard to type in Hebrew characters?
There is no way of answering your question correctly, because it depends on the system you use. The easiest way is to google exact instructions for the device you have.
If you are using Windows 10 (which most people do): type Add Language into Cortana's search bar, and follow the prompts. Once installed, you can (by default) switch keyboard layouts by pressing ALT-SHIFT.
I bought my Hebrew keyboard stickers on eBay, but they probably sell them in thousands of other places:
Just my opinion... Stickers are not a great idea.
You are better off, in my opionion, to either draw a pic of hebrew keyboard and place at monitor level or enable an onscreen keyboard either through accessibility or by using the duokeyboard extension.
The habit of looking at one's fingers is to be avoided whether on a typewriter, at the guitar, piano or on duolingo.
Consider this: if you have stickers, no-one forces you to look at them; however, if you choose to look, you can. Without stickers, you have no such choice.
I learned to touch-type on QWERTY by just typing (looking less and less as the muscle memory set in). For Cyrillic layout, I did use a special exercise book. I don't see any difference in the results, though. For Hebrew I am using the natural method.
