Improves the new `Editor::DuplicateSelection` @CharlesChen0823 added in
https://github.com/zed-industries/zed/pull/21154.
- Merge `duplicate_selection` and `duplicate_line` into single function.
- Add keyboard shortcuts to JetBrains and SublimeText keymaps.
- If the selection is empty (e.g. just a cursor) make
`Editor::DuplicateSelection` fallback to being the same as
`Editor::DuplicateLineDown`.
- Tested with multiple cursors and for multiple selections.
| Editor | Action | macOS | Linux |
| ----------- | ------------------- | ----------- | ------------ |
| VSCode | Duplicate Selection | | |
| JetBrains | Duplicate Selection | cmd-d | ctrl-d |
| XCode | Duplicate | cmd-d | N/A |
| SublimeText | duplicate_line | cmd-shift-d | ctrl-shift-d |
This matches behavior of the `duplicate` functionality in all other
major editors, with one exception: other editors change the selection so
that the newly duplicated object, current Zed behavior leaves the
original selection unchanged (TODO?)
JetBrains IDE's use `ctrl-w` and `ctrl-shift-w` on Win/Linux and
`cmd-up` and `cmd-down` on mac to extend/shrink selections.
