I wanted to type part of a filename, press Tab, and get the right file—even when that text appears in the middle.
Two things make this comfortable: Zsh’s matching rules and the fzf-tab picker.
Add this to ~/.zshrc, after your existing completion setup:
| zstyle ‘:completion:’ matcher-list ‘m:{a-zA-Z}={A-Za-z} l: | = r: | =*’ | This enables case-insensitive substring completion. For example:
hx zero → hx GROUND_ZERO.md hx fuego → hx 2026-10-14-hyprfuego.md
No need to type the beginning, remember the capitalization, or work around a date prefix. This part uses Zsh’s built-in completion system.
fzf-tab (https://github.com/Aloxaf/fzf-tab) adds an interactive fuzzy search menu to Tab completion. It uses the candidates supplied by Zsh.
If several filenames contain zero, typing: hx zero
opens a picker. Keep typing to filter the results, use the arrow keys to choose, and press Enter to insert the filename.
You can also start without a fragment:
hx
Then type something like shapes inside the picker to find a matching file. Enter inserts it; another Enter runs the command. Esc cancels.
