Move cursor by sliding on the space bar

Send key events for the left or right arrow as the finger slides on the
space bar.
Can be used to select text by holding shift. Works under Termux.

Events are sent linearly as the finger travels. The distance between
each events is defined from the swiping distance divided by 4.

'slider="true"' can be set on a key that have 'edgekeys="true"'.
'key2' and 'key3' represent the right and left keys.
