Arrow keys:

up: move the cursor up
down: move the cursor down
right: Enter into directory
left: Leave directory

For vimmers, h, j, k, l are mapped to the arrow keys as you'd expect from any vim inspired program.

Search

Press / and then type any regular expression to search files and folders in the current working directory.
While in search mode, you can use up or ctrl-p to move the cursor up, and down or ctrl-n to move the cursor down. Use left, right keys to enter into or leave directories without leaving the mode.
When you are done, press enter to leave the search mode.
Alternatively, install fzf.xplr if you are a fzf user. Or install zoxide.xplr to be able to jump between your most visited directories using zoxide.

UPDATE: Since v0.19.4 xplr search defaults to fuzzy search (plain text/characters), but you can still use regex-search.xplr plugin to utilise regex based search.

Jump to index
