 - You can switch between OCR providers pressing their corresponding keyboard key inside the terminal window (refer to the list of keys in the providers list below)
 - You can start the script paused with the `-p` option or with a specific provider with the `-e` option (refer to `owocr -h` for the list)
 - You can specify keyboard combos in the config file to pause/unpause and switch the OCR provider from anywhere (refer to the config file or `owocr -h`)
-- You can auto pause the script after a successful text recognition with the `-a=seconds` option if you're not using screen capture. 0 (the default) disables it.
+- You can auto pause the script after a successful text recognition with the `-a=seconds` option. 0 (the default) disables it.
 - You can enable notifications in the config file or with `-n` to show the text with a native OS notification if you're not using screen capture with automatic screenshots. **Important for macOS users:** if you use Python from brew, you need to enter this command in your terminal before the first notification: `codesign -f -s - $(brew --cellar python)/3.*/Frameworks/Python.framework` (works on Ventura/Sonoma). Older macOS versions might require Python to be installed from the [official website](https://www.python.org/downloads/). Nothing can be done about this unfortunately.
 - Optionally, you can speed up the online providers by installing fpng-py: `pip install owocr[faster-png]` (requires setting up a developer environment on most operating systems/Python versions)
 - A config file (which will be automatically created in `user directory/.config/owocr_config.ini`, on Windows `user directory` is the `C:\Users\yourusername` folder) can be used to configure the script, as an example to limit providers (to reduce clutter/memory usage) as well as specifying provider settings such as api keys etc. A sample config file is also provided [here](https://raw.githubusercontent.com/AuroraWright/owocr/master/owocr_config.ini)
