See [`modal` example](./examples/modal.rs) for working example. It implements more Vim-like key mappings.
|
||||
|
||||
If you don't want to use default key mappings, `TextArea::input_without_shortcuts()` method can be used instead of
|
||||
`TextArea::input()`. The method only handles very basic operations such as inserting/deleting single characters, tabs,
|
||||
newlines.
