 7# This script opens a new, temporary tmux pane and runs n-history. When
 8# a selection is made, the result (history entry) is pasted back into
 9# original tmux pane, and the temporary pane is closed. This allows to
10# use local history on remote machines.
11#
12# To use, put this line to your ~/.tmux.conf. The tool is invoked with:
13# Ctrl+b h
14#
15# bind h run-shell -b "$ZNT_REPO_DIR/doc/znt-tmux.zsh"
