[FEATURE]: Allow to expand the pasted text (e.g. `[Pasted ~1 lines]`)

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

The problem

I love that pasted text is summarized to avoid bloating the prompt, but I usually want to edit it or at least view it before sending the prompt.

This is especially inconvenient when using voice-to-text.

The current workarounds

• I know I can use my editor (leader + e) to edit text, but it's not as convenient for small edits.
• I know there's an experimental flag experimental.disable_paste_summary to disable this but I want to toggle it on and off easily.

Potential solution

I wish I could use a keybind to expand and see it's contents right there.

Update

I implemented it in:
