Alt or Ctrl + left/right arrows behaves incorrectly

[leviport]

Alt or Ctrl + left/right arrows should move the cursor forward or backward 1 word. Currently, it moves the cursor forward or backward by one character and inserts unwanted characters. Ctrl + arrows inserts ;5 and alt + arrows inserts ;3

To recreate:

• In a terminal, type a few words separated by spaces
• Hold alt or ctrl, then tap the left arrow

Shift + arrows also doesn't select text as expected.

I'm interested in working on this, but I need a bit of guidance on where this behavior should be handled. I assume

cosmic-term/src/terminal_box.rs

Lines 641 to 654 in 7c5d544

	Named::ArrowRight => {
	if is_app_cursor {
	ss3("C", mod_no)
	} else {
	csi("C", "", mod_no)
	}
	}
	Named::ArrowLeft => {
	if is_app_cursor {
	ss3("D", mod_no)
	} else {
	csi("D", "", mod_no)
	}
	}

is doing exactly what it's supposed to, and those control codes should be received and handled somewhere else? I'm just not sure where control codes are actually turned into cursor and selection modifications. Clearly somewhere the codes for arrow keys without modifiers is being handled and moving the cursor, but it's failing to handle modifiers. I just don't know where that is.
