# v0.5.0 — Terminal search, keyword alerts & a major TTL scripting upgrade

## ✨ New features

**Find text in your scroll-back (Ctrl+F)**
* Press **Ctrl+F** to open a search bar right inside the terminal and find any text in the
  scroll-back history — **Enter** jumps to the previous match, **Shift+Enter** to the next,
  **F3** repeats, **Esc** closes.
* Every match is highlighted in **yellow**, the current one in **orange**, and matches stay
  anchored to the right line even as old output scrolls off the top of the buffer.

**Keyword highlighting + per-tab alerts**
* Define your own keyword list under **Settings → Highlight** (add, remove, and enable/disable
  each one). Matching text is highlighted on screen wherever it appears, case-insensitive.
* When a keyword shows up on a tab you're **not** currently looking at, that tab's dot turns
  **red** so you notice it — switching to the tab clears the alert. Great for watching several
  sessions at once for an error string.

**A much bigger, TeraTerm-compatible TTL scripting language**
* The TTL engine now understands a large set of **TeraTerm-compatible commands**, so many
  existing TeraTerm macros run with little or no change.
* New control flow — `for`/`next`, `do`/`loop`, `while`/`until`, `call`, `goto`, `break`,
  `continue`, `include` — plus a real expression parser (parentheses, logical & comparison
  operators, hex `0x` / `$`), and dozens of new string, file/folder and utility commands
  (`sprintf`, `strsplit`, `filereadln`, `getdate`, `random`, `crc32`, `inputbox`, `yesnobox`, …).
* New **serial-specific** script commands: `sendbreak`, `setbaud`, `setdtr`, `setrts`, `sendfile`.
* Note: a single-string `wait` keeps ETTerms' existing settle-and-timeout behavior; multi-string
  `wait` follows TeraTerm semantics (times out and continues with `result=0`).

**See — or hide — what your scripts are doing**
* Scripts now echo their progress (waits, sends, errors) in **grey** directly in the terminal,
  and you can switch this off under **Settings → Terminal** (**Show script trace**).
* The trace is display-only: it never reaches your session log, the AI bridge, or the device,
  so your captured machine logs stay clean.
