 A row's default height is 1.0 (one quarter of the keyboard height specified on the Settings menu). The `height` property makes the row taller or shorter than this. For example, if you define a 5-row keyboard but one row has `height="0.7"`, then the keyboard's total height is 4.7 units. If the total is different from 4.0, the keyboard will be taller or shorter than that specified in Settings.

 The `<key />` tag defines a key on the keyboard. Its position in the sequence of keys inside `<row>`...`</row>` indicates its position in the row from left to right. What the key does is defined by optional properties.
