This keyboard lets you type in Bengali (Bangla) and Assamese. It is one of the ISIS set of keyboards, which allow typing in all Indian languages. The keyboard is phonetic, which means it follows the English (QWERTY) layout. This makes it easy for people who are learning Bengali to use, as well as for Bengali speakers.
If a special font is needed for this language, most computers will download it automatically.

Using this Keyboard
Anybody who is familiary with a normal English keyboard can used this keyboard to type Bengali. If you press an English letter, the closest Bengali character will be displayed. You can type long vowels by pressing the vowel key twice. Bengali includes some consonants and vowels which are not in English, so these are typed with spare keys or with [S*].
Most Bengali characters have both consonant and vowel parts, and each part should be typed separately. The consonant part is always typed before the vowel, no matter where the vowel part is written. For example, typing i will produce the vowel ই. If this vowel is typed after a consonant has been typed, it will be combined with a consonant, such as কি,(ki). If you press Backspace once, only the vowel part will be erased, and you can type a different vowel.
The On Screen Keyboard shows the standalone vowels অ আ ই ঈ উ ঊ এ ঐ ও ঔ, and many of the normal consonants: ক গ চ জ ট ড ণ ত দ ন প ব ম য় র ল ষ স হ ড়. Other consonants are typed using more than one key. The keyboard also includes Bengali numbers, as well as punctuation and special characters.
Bengali vowels and consonants are usually combined, so when you type a consonant and a vowel part, they will be joined into one character. If you use the arrow keys to move through the text, you only need to press an arrow key once to move past each character. If you press Delete before (on the left of) a combined consonant and vowel, it will be erased completely, but if you press Backspace after a character, only the vowel part will be erased (even if the vowel part appears before the consonant).
Vowels and Consonants
When you type consonants and vowel parts, you should always type the consonant part first, even when the vowel part appears on the left of the consonant. If you type any of the independent vowels, they will not be combined with consonants.
All the consonants naturally include the vowel sound অ, so if you want to produce a consonant with no vowel, you need to add the ্ mark. You can do this by typing \ right after typing a consonant. After you have typed the ্ mark, you cannot type a vowel to combine with that consonant.
Bengali includes many combined consonants, and these are not shown on the keyboard. To type a combined consonant, type the first consonant, then the ্ mark, then the second consonant. The computer will then combine the two consonants into a single combined character. For example, typing k\k produces the combined consonant ক্ক.
In the following table you can see examples of how to type the different vowels with the consonant ক. For a table of all the normal Bengali characters and how to type them, click here.
If you see squares when you type, or the Bengali characters do not appear correctly, please read the KeymanWeb troubleshooting guide.
If a vowel does not combine with a consonant, make sure you have typed the consonant first. Also check that you have not typed another vowel already, or the ্ mark.
