Let me start with the first section:

So each word in this sentence (excluding punctuation) would need three synonyms. Let's take "Add" first: Insert. "arrows" could be pointers, "text" as script, "annotations" as markups, etc.

I need to ensure that only terms with three options are replaced, and brand names are left as is. Also, the user said to return text only, so no markdown. So the answer is the text with the replacements.

: Add arrows, text, and other annotations to your captured images and videos.

Looking at the system requirements: "make sure your computer meets the system requirements." "Make sure" could be Ensure, "meets" as satisfies. Then under Windows: "64-bit" stays, but "Windows 10, 8, or 7" remain as they are. "4 GB RAM" is okay, but "hard drive space" might become hard drive space.

Original: :Add arrows, text, and other annotations to your captured images and videos.

1. Screen Capture: three options: entire windows, selected regions, scrolling windows. Replace with selected regions.
