Is there a quick way to search old commands which were run in the Julia REPL? Using the up arrow to go back in time seems to have a limit on its history and it is also quite cumbersome.

One of the five REPL models available in Julia is the "Search mode" which allows you to search through previously executed commands from the REPL. You can click "Control" + "r" to open search mode like is shown below:

(reverse-i-search)`':

There is also a forward search available with "Control" + "s". You can read more about Julia's REPL Search mode here: https://docs.julialang.org/en/v1/stdlib/REPL/#Search-modes

In addition to "real" search, you can also enter the beginning of a previous line and scroll up in the history (using ↑ or Ctrl-P) to switch between all previously entered lines starting with the same prefix.

So, if you had previously entered x = some_complicated_expression, you can write x = and go up until the line you were looking for appears.
