In this part we let users to switch task statuses.
At first, there should be available commands:
type Command = Move `S` Mark
pattern Move x = This x
pattern Mark x = That xWe can introduce such an internal convention - lowercase letter commands do not change the state:
apply = is @(ASCII `MN` Glyph `S_` Glyph `MN` Letter) `hu` by Wrong
`la____` press `hv` Lower J `hv` (Move `ha` Down)
`lo'ys'la` press `hv` Lower K `hv` (Move `ha` Lift)
`lo'ys'la` press `hv` Upper T `hv` (Mark `ha` TODO)
`lo'ys'la` press `hv` Upper D `hv` (Mark `ha` DONE)The last step - interpretation. We can switch a focused task’s status, but we should zoom in a modified state:
`yok___` State `ho` New `ha__` Event `ha` (scroll `ho'ho'yui` Unit)
`la___` State `ho` New `ha__` Event `ha` (switch `ho'ho'yui` Unit)
`ho_'ha'he` Scope `hv` at @(Focused Task) `ho'he` (Scope `hv` at @Mark)Next time we will introduce subtasks.
