Add a switchers chapter and fix drift found on a second manual pass

Add "Coming From Mac or Windows" as chapter 3: a translation layer for
Cmd/Win instincts rather than a feature tour.

Fill the remaining coverage gaps: fcitx5 input methods, laptop speaker
tuning, touchpad haptics, crash capture in the toggle table, the
installable font list, and the ChatGPT Desktop and Grok Bot entries.

Correct claims that drifted from the source: the network and bluetooth
bar icons no longer launch nmtui/bluetoothctl, monitor scaling steps
rather than cycles, and the display widget's scroll steps brightness.

+# Text Extraction & Dictation
+
+### Text Extraction
+
+Hit `Super + Ctrl + PrtScr` to select a region on the screen for text extraction. The tesseract open source OCR model will then quickly convert that selection into text and place it on the clipboard. Then you just hit `Super + V` to paste.
+
+This is very helpful for grabbing addresses out of image footers or phone numbers embedded in website headlines.

+
+### Dictation
+
+Omarchy offers AI dictation via [Voxtype](https://voxtype.io/). You install it via _Install > AI > Dictation_ through the Omarchy menu. By default, it'll load a base English model that takes up 150MB. But you can tweak which model you'd like to use by running `voxtype setup model` in the terminal. And you can tweak all the settings via `~/.config/voxtype/config.toml`.
+
+Once installed, you dictate by holding down `F9` or by toggling with `Super + Ctrl + X`, and the dictated text will appear in the focused input area.
