<h1><strong>HOME ROW KEYS (KEYBOARDING APPLICATIONS)</strong></h1> CONTENT <ol> <li>Correct Finger Position on the Home Keys</li> <li>Correct Finger Movement on the Home Keys</li> <li>Correct Ways for Finger Position on the Top Row, Upper Row, Home Row and Nottem Row</li> <li>Correct Finger Position and Movement for Special Characters and Figures</li> <li>Two Divisions of the Keyboard</li> </ol>   <strong>NOTE</strong> – Identification, demonstration, manipulation/application of the keyboard rows are to be done majorly here. Students are to: <ul> <li>Observe the position of the four rows of the keyboard (Top, Upper, Home, Nottem) and point them out as shown to them by the teacher.</li> <li>Practice proper finger placement on the home row keys as demonstrated by the teacher.</li> <li>Practice how to manipulate the home row keys using soft touch as demonstrated by the teacher</li> </ul> <h2><strong>Correct Finger Position on the Home Keys</strong></h2> The four fingers excluding the thumb of the left hand are placed on “asdf” while the four fingers of the right hand are placed on ";lkj". It is from here that the fingers move up and down the entire keyboard. “asdf and ;lkj” are therefore called home keys. First of all, master the keyboard to know the positions of the keys, and then type without looking at the keyboard but the copy. <h2><strong>Correct Finger Movement on the Home Keys</strong></h2> After placing the fingers on the home keys, the fingers should strike a key at a time to avoid key jam. The two little fingers are used to strike the guide keys (a & ;). The remaining fingers on the left except the left and right thumb are used to strike “sdf” while the rest fingers on the right hand are used to strike “lkj”. Activity: Practice exercise 1 from Walmsley’s Commercial Typewriting by Aileen M Prince <h2><strong>Correct Ways for Finger Position on the Top Row, Upper Row, Home Row and Nottem Row </strong></h2> <h3><strong>The Top Row</strong></h3> Figures play one of the most important parts in typewriting. Since numerical errors in any piece of typewritten work may cause much harm, therefore maximum concentration on the correct fingering in the very early stages of training is very important to attain that degree of efficiency required.

<h1><strong>ALPHANUMERIC KEYS (KEYBOARDING APPLICATIONS)</strong></h1> CONTENT <ol> <li>Alphanumeric keys</li> <li>Identification of Alphanumeric Keys</li> <li>Correct Finger Placement on Alphanumeric Keys</li> <li>Soft Touch Manipulation of Alphanumeric Keys</li> </ol> <strong> </strong> <h2><strong>Alphanumeric Keys</strong></h2> These are keys of all the alphabets (a – z) and numbers (0 - 9). The alphanumeric keys also include symbols at the upper part of the number row such as exclamation mark (!), at (@), ampersand (&) etc. <h2><strong>Identification of Alphanumeric Keys </strong></h2> Here, learners are to properly identify all the alphanumeric keys. The keys are to be shown to the learners by the teacher. <h2><strong>Correct Finger Placement on Alphanumeric Keys</strong></h2> For fingers to use on alphabets, refer to the previous lesson i.e week 6 on keyboard rows particularly the areas highlighted in yellow colour above. For the numeric keys, the 1st finger on the left hand side will press key ‘‘4’’, the 2nd finger will press key ‘‘3’’, the 3rd finger will press key ‘‘2’’, while the 4th finger which is the little finger will press key ‘‘1’’.

<h1><strong>BASIC SERVICE KEYS (KEYBOARDING APPLICATIONS)</strong></h1> CONTENT <ol> <li>Basic Service Keys</li> <li>Correct Finger Placement on the Basic Service Keys</li> <li>The Manipulation of the Basic Service Keys Using Soft Touch</li> </ol> <strong> </strong> <h2><strong>Basic Service Keys </strong></h2> These are special keys that allow you to use computer to perform specific functions. Examples are: space bar, tab key, caps lock key, control key, shift key, delete key, return key, Alt key, home and end, insert and arrow keys. <h2><strong>Correct Finger Placement on Basic Service Keys</strong></h2> (i) <strong>Space bar:</strong> Although both thumbs are placed on it but the right thumb is used to press it when typing. (ii) <strong>Tab key:</strong> The 4^th finger (little finger) on the left hand is placed on it and used to press it. (iii) <strong>Caps lock key:</strong> The 4^th finger (little finger) on the left hand is placed on it and used to press it.
