Exercise 3: Try Every Prefix — Possible Solution
====================================================================

STEPS
------------------------------
1. Open Quick Open with Ctrl+P.
2. Type ">" (greater-than). The box relabels itself and now shows the
   exact same command list as Ctrl+Shift+P's Command Palette —
   confirming the chapter's own claim that they're literally the same
   underlying search box.
3. Clear the box, reopen Quick Open, and type "@". With a code file
   open, this shows a list of that file's own symbols — functions,
   classes, or variables defined in it — letting you jump straight to
   a definition instead of scrolling to find it.
4. Clear and reopen, then type "#". This searches symbols across
   EVERY file in the open folder, not just the current one — typing
   part of a function name here can find it even if you don't
   remember which file it lives in.
5. Clear and reopen, then type ":" followed by a number (e.g. ":15").
   This jumps directly to line 15 of the currently open file, the
   same line-jump behavior from the Status Bar exercise in Chapter 1,
   now reachable from Quick Open as well.

WHAT TO NOTE
------------------------------
Each prefix completely changes what's being searched, but the
underlying box, keystroke, and result-list UI stay identical across
all four modes — only the interpretation of what you type changes.
The "@" and "#" modes are noticeably more useful once working in
larger files/projects with many functions, since they replace manual
scrolling or Explorer-clicking with a direct, named jump.

WHY THIS WORKS AS AN ANSWER
------------------------------
Working through all four prefixes hands-on, one at a time, reinforces
the chapter's own comparison table directly — rather than just
reading that ">" opens commands, @ searches file symbols, # searches
workspace symbols, and : jumps to a line, actually triggering each one
confirms the behavior and builds the habit of reaching for the right
prefix depending on what's actually being searched for.
