Changing Table Type
Note: A normal user need not change anything here. This option is only for the advanced users wishing to change text to Braille and vise versa.
3.1 Simple Mode Editing
You can activate the simple mode edit check box by pressing tab and pressing space bar on that check box. Simple mode editing is an option which prevents a user from using contraction forwards. For example pressing the letter ‘f’ and then pressing the contraction key will enable the user to write the word from. Like wise pressing contraction key dot5 and then typing letter ‘f’ will give the word father. Beginner will not be able to use word contractions as mentioned if the simple mode check box is checked. However the contractions used in between a word will be in use. For example dot2 is used to write ‘ea’in between a word. You can write the word ‘peace’ by typing the letter ‘p’ then pressing dot2 to insert the letters ‘ea’ and then typing ‘ce’. Another example is the word ‘however’. You can type ‘however’ by typing ‘h’ then pressing dot2,4,6 to insert the letters ‘ow’ and then typing ‘ever’. This feature is especially added for the children who learn Braille typing.
3.2 Conventional Braille Mode
You can get to this option by pressing tab. You will find a checkbox to switch between conventional Braille mode and normal Braille mode. This checkbox will be unchecked by default. If this checkbox is activated, conventional Braille mode will be in operational. In this mode you can press dot4 and the letters to double. For example (in Malayalam) dot4 is pressed and the dot1 and dot3 are pressed together twice to get the pronunciation kka(ക). To write the word ‘pokki ‘ in Malayalam you can type the letter Malayalam pa, Malayalam letter o, pressing dot4 once and then typing the Malayalam letters k twice and then pressing the letter dot2,4 for Malayalam i. In the case of normal Braille mode dot4 comes in between the doubled letters. For example , to write the word ‘pokki’ in Malayalam you will have to type “p o dot1,3 then dot4 then dot1,3”. Then dots2,4 for Malayalam i. Normal Braille mode feature is provided to make the user better understand the way of write in the sighted. In other words one can easily understand the way a sighted person writes the above mentioned words.
3.3 One Hand Mode
You can get to one hand mode by pressing tab to find the one hand mode check box. This check box enables a writer to use single hand. In Braille normally two hands are used to type dot 1,2,3,4,5,6. A person who can only use a single hand can type with one hand using the one hand mode. For example to type the letter ‘d’, normally one presses dot1 with a left hand and dot4,5 together with the right hand. This is not possible in the case of a person using single hand. One hand mode is used to overcome this barrier. For example to type the letter ‘d’ that person can press dot1, wait for a
second and then press dot4,5 together. Here dot1,2,3 (fds) becomes dot4,5,6. The delay can be adjusted according to the need of the use. This can be done by pressing tab getting to the delay slider and using up and down arrow keys.
