This change allows defining keybindings that are active when there is a
text selection.
This is especially useful, as an example, for Emacs-like keybindings
where movement keybindings expand the selection.
Here is a snippet from my keymap.json that implements Emacs movements
when selection is active:
```json
{
"context": "Editor && selection",
"bindings": {
"ctrl-f": "editor::SelectRight",
"ctrl-b": "editor::SelectLeft",
"ctrl-n": "editor::SelectDown",
"ctrl-p": "editor::SelectUp",
"ctrl-a": "editor::SelectToBeginningOfLine",
"ctrl-e": "editor::SelectToEndOfLine",
"alt-f": "editor::SelectToNextWordEnd",
"alt-b": "editor::SelectToPreviousWordStart",
"alt-<": "editor::SelectToBeginning",
"alt->": "editor::SelectToEnd"
}
}
```
What do you think about inclusion of this feature? Should I add more granular `selection=single` `selection=multi`?
Release Notes:
- Added "selection" context for keybindings that are active when there is a text selection.
