shift g: goes to end.
shift f: tails the file.

  – ctrl+c: switch to normal mode (no tails)

?: search upwards
/: search downward
 – n: search next match in current direction
 – shift n: search next match in counter direction
Also useful to find 2 or more words in one line is the regex:
Word1.+Word2 finds both words in the same line
As an extra to review logs, it is also useful the command grep with options after and before:
grep -A: lines after match
grep -B: lines before match
