Characters with fewer than 4 components (needing strokes) Example 3a: 文: First you type the key with the symbol on it, which happens to be 'Y'. Then you type the first component, which is also 'Y' for the 点 stroke, then a 'G' for the 横 stroke，and since you now already have three strokes, you type the last stroke, which also happens to be a 捺, arriving at the keycode 'YYGY' for the complete character.
