Please describe the problem you're trying to solve

Missing keybinds, for dialog inputs:

• r to replace a single character.
• _ and ^ to jump to the first non-whitespace character in the line.
• W to jump to the next WORD start.
• B to jump to the previous WORD start.
• E to jump to the end of the next WORD end.

'WORD' here meaning a sequence of characters delimited only by whitespace, not punctuation.

Would you be willing to contribute this feature?

• [X] Yes, I'll give it a shot

Describe the solution you'd like

Implement these keybinds for dialog inputs.

Additional context

Similar to #770.

Additionally, I jumps to the first character in the line, instead of the first non-whitespace character. This is not consistent with vim, so I will open a separate bug report for this.

Checklist

• [X] I have searched the existing issues/discussions
• [X] The latest nightly build doesn't already have this feature
