What this lesson covers

Numbers and punctuation are the under-trained part of every typing curriculum. Yet 8 per cent of SSC Hindi passages are numbers and dates. If you cannot type 2,547 fluently, you slow down at the worst moments.

Kruti Dev has one quirk new typists trip on: the Z key is the period (पूर्णविराम / .), not the dot key on the bottom-right. The dot key in Kruti Dev produces a different glyph. Typing the period reflexively as a dot is a 5-WPM-killer.

Similarly, the X key is comma in Kruti Dev. Real comma. Not the comma key. Lesson 6 drills these into reflex.

Drills — type along, do not skip

Why this lesson matters

The Z-period rule kills aspirants who otherwise can type. They reach the end of a sentence, instinctively hit the dot key, and produce a meaningless symbol. The "error" registers in Net WPM. Drill the Z key now until it is automatic.

Most online Krutidev tutorials skip this lesson entirely. It is the cheapest win in the whole curriculum. Four days, 25 minutes a day, fixes a 3-WPM gap.
