When my mother needs to type in Hebrew (such as when finding all of the great deals she posts here), she always uses my program.
Here's something I wrote up about it:
Have you recently needed to type in Hebrew, but couldn’t, because of your keyboard language? Well, there’s a way to add it, but it can be difficult. I made a program that lets you do it, with no downloads, whether you use Windows, Mac, or Linux. It even works on phones! This is a virtual keyboard named TypeR. Not only does it simulate a standard Hebrew keyboard, it even lets you add vowels (nekudot)! To use this feature, simply press ctrl+alt, and choose one.
This wonder keyboard is completely free. You can view the website at http://www.typeint.com/. The program itself is at http://www.typeint.com/typer/. I also maintain a blog about the site: http://typeint.com/blog.
I’d love feedback on the TypeR keyboard and the website as a whole. I’m also constantly working on it, fixing the few bugs that crop up, and more importantly, adding features. Right now, the next version is nearly done, with several new features. I’d appreciate it if some people would beta test it. Don't worry, it almost always works, and even works better than the old version! http://blog.typeint.com/2013/02/typer-12-is-now-in-beta.html
I hope you find this as useful as i do!
