Place your caret on the word or text range you want to find and select multiple occurrences of and then use ⌘⌃G (macOS) / Ctrl+Alt+Shift+J (Windows/Linux) to find and select the next occurrence of the word. This is a case-sensitive search. You can use ⌘⌃G (macOS) / Ctrl+Alt+Shift+J to select all matching words in the document rather than selecting one at a time. You can use ^⇧G (macOS) / Alt+Shift+J (Windows/Linux) to remove the selection from the last selected occurrence. To skip an occurrence, use ⌘G (macOS) / F3 (Windows/Linux) and to go back to the last selected occurrence, use ⇧⌘G (macOS), or Shift+F3 (Windows/Linux).
