## `size' to sort them by the size of the file
## `links' to sort them by the number of links to the file
## `modification' or `time' or `date' to sort them by the last modification time
## `access' to sort them by the last access time
## `inode' or `change' to sort them by the last inode change time
## `reverse' to sort in decreasing order
## If the style is set to any other value, or is unset, files will be
## sorted alphabetically by name.

## case-insensitive (uppercase from lowercase) completion
#zstyle ':completion:*' matcher-list 'm:{a-z}={A-Z}'
## case-insensitive (all) completion
