The current horizontal chunk motion (ctrl + left/right arrow by default) does not work like most other editors, subverting the users expectation. The behaviour of most editors from my experience is as follows:
1. Skip any leading whitespace in the motion
2. If the next char is:
- Alphanumeric or `_`, move up until the next symbol that isn't one of those
- not one of the above move either up until: the next whitespace character or the same rules as above if an alphanumeric or `_` is encountered before whitespace.
e.g. Assume the current cursor position and string `... |mystruct.member ...`
The current code will move to the end of the whole struct accessor: `... mystruct.member| ...`
Most other editors would move to the end of the struct name: `... mystruct|.member ...`
In this case the current behaviour may not seem _that_ agregious, but in other cases its much more annoying
especially if you're looking to copy into a watch window or something as in this case:
`|ui_nav_scanned_column_from_column(String8 string, ...)`
the cursor will move to: `ui_nav_scanned_column_from_column(String8| string, ...)`
which is almost certainly not what the user wanted.
This behaviour means that if you want to copy a symbol, you can consistantly achieve this by chunk moving to one end, pressing shift, then chunk moving to the other end without ever getting extra symbols/whitespace. This is currently not possible with existing chunk motions.
