feat: word-based text navigation and deletion

Feature Request: Implement Word-Based Text Navigation and Deletion

Description:
Introduce standard keyboard shortcuts using modifier keys (Alt/Option, potentially Cmd depending on platform standards) for word-level operations within text input fields. This includes moving the cursor word by word and deleting entire words at a time.

Motivation:
Currently, navigating and editing text often requires character-by-character actions, which is inefficient for larger edits. Implementing word-based shortcuts aligns with standard OS-level text editing behaviour, significantly improving editing speed and user experience.

Acceptance Criteria:

1. Cursor Movement:

• Pressing Alt/Option + Right Arrow moves the cursor to the beginning of the next word.
• Pressing Alt/Option + Left Arrow moves the cursor to the beginning of the current or previous word.

1. Word Deletion:

• Pressing Alt/Option + Backspace deletes the word immediately preceding the cursor (and any preceding whitespace).
• Pressing Alt/Option + Delete (or Fn+Alt/Option+Backspace on some keyboards) deletes the word immediately following the cursor (and any following whitespace).

1. Selection (Optional but Recommended):

• Combining Shift with the Alt/Option + Arrow Key combinations selects text word by word.

Usage Examples:

1. Correcting a typo:

• User typed: "Hello brave neww world"
• Cursor is at the end.
• Press Alt/Option + Left Arrow once -> cursor moves before "world".
• Press Alt/Option + Left Arrow once more -> cursor moves before "neww".
• Press Backspace once -> deletes the extra 'w'.

1. Deleting a word:

• User typed: "This is some sample text"
• Cursor is after "sample ".
• Press Alt/Option + Backspace once -> deletes "sample " -> "This is text".

1. Replacing a word:

• User typed: "Use the blue button"
• Wants to replace "blue" with "green".
• Place cursor before "blue".
• Hold Shift + Alt/Option, press Right Arrow once -> selects "blue ".
• Type "green " -> replaces selection -> "Use the green button".
