Support word/line deletion

[rlivsey]

option+backspace on OSX should delete the word to the left, this is ctrl+backspace on Windows & Linux IIRC.

Likewise cmd+backspace on OSX should delete to the start of the line, I'm not sure what the Windows/Linux shortcut for this is…

Thanks for opening. This should definitely be added.

I wonder if the standard behaviour is documented anywhere, or if there are other projects which do this we can crib from. It's not a simple as "delete up to the closest whitespace character" unfortunately.

Certain non-whitespace characters (eg :) look to be treated as part of the word, whereas others (eg +) aren't:

Quick experiment results, where | is the cursor:

before	after
foo bar `	`
foo+bar `	`
foo:bar `	`

Possibly "just" a case of coming up with a whitelist of characters to treat as separators or not.

Interesting. I also found this apple doc that shows some other common movement commands.
Whitelisting word-separators seems like a fine way to go. I experimented briefly just now and can find only one other separator that is ignored like the colon is: the underscore.

Cool, that's hopefully fairly straightforward then. I'll take a stab at it tomorrow as it's probably a good task to get my head around section editing etc…

The same goes for option + shift + left/right arrow for highlighting an individual word or or cmd + shift + left/right arrow for highlighting a whole line.

the word and line cursor movements are implemented as of v0.10.0. Supporting option-delete is in progress...
