Question: I can't tell from the picture- are the english letters still visible or does it change it over to show Hebrew only?
Document: I was afraid that it might be all black but it was not. Black keys on clear. I love it! It is very soft to touch and won't slip or move as I type. Hebrew letters are printed larger than English letters in the centers of the keys and easy to find. The nikdots are harder to see in the image here, but they are there on the number keys, clearly printed. The letters look like they were there originally; hard to tell when it is on.
this keyboard is everything i wanted and is described here all letter are nice and big and fits my every need for this .the only thing i would change is to make the hebrew letters small and the english one big , the big hebrew letters makes it hard to focus on the english letter and each time i need to write in english i have to take the &#34;keyboard&#34; off i would like to keep it on all the time .
I like the cover so much more than stickers. The Hebrew and English letters are very clear to read. It fits perfectly over my keyboard and protects it, too. I do feel like it slows down my typing, however, and when I want to type something very quickly, I usually remove it.
This Hebrew keyboard cover fits perfectly over the keys of my MacBook Pro. As stated by another reviewer, the Hebrew letters are the larger, more dominant letters on the keys. This works great for me because I know the English layout just fine. The keyboard cover seems a little chaotic at first since there are so many markings, but I quickly got adjusted to the difference.
I have tried to use even the standard key board protectors and they were too thick and difficult to type with. Not only do I make use of the easy to see Hebrew letter when I am typing in Hebrew, I use it for my english letters as well, for I can type English without looking at the key any way...thanks to the old fashion typing classes I took in HS in the 70's.
Stickers are very messy, so I gave up after sticking just 2 letters (and was hard to remove them too). This silicon cover is the way to go. It does not interfere when I close my Mac, or damage the screen. After only a week or so, I am used to typing regular English words also with this cover on, so I am just leaving this on; don't want to remove it. It will also protect my Mac from the dust. Shipping was very fast also.
This is just what I needed to be able toTranslate Hebrew to English. It did my MacBook Air 13 just right.
I love the quality and layout of this keyboard cover as the Hebrew letters are the larger, dominate letters. By purchasing black, the original keys do not shine through, yet the backlight for the keys works well. Would have given 5 stars, however the cover doesn't fit well over the keys on my rMBP13. Aside from that, great quality in the material. Will last much longer than the clear covers I've purchased in the past.
This is a good product which does what it needs - gives you the ability to write Hebrew on a Mac. But the rubber doesnt work that well for me and I take it off when I need to work on english -there is no replacement to work dirrectly on the Apple KB
The only problem is that covers like these slow down your typing quite substantially. Since I'm a slow Hebrew typist, it doesn't matter for me. If I were a native speaker/writer, as with the similar cover I have for English, it would keep the keyboard clean but slow me down greatly.
Answer: English letters are printed there along with the Hebrew.
