Print the character before and after the cursor

I need a zle function that will print the character before and after the cursor. print-char-before-after() { # Get the position of the cursor local cursor_pos=$CURSOR # Get the text in the current line local line_text=${BUFFER} } # Bind the function to a key combination (for example, Ctrl+P) zle -N print-char-before-after bindkey '^P' print-char-before-after Considering the pipe to be the cursor, if input is: This is a inp|ut The output will be pu It needs to work on beginning and end of line and also on multiline buffer. if input is: |This is a input The output will be T if input is: This is a input| The output will be t How can I do that? **UPDATE 1:** The code that sort of solves my problem is: print-char-before-after() { # Get the characters from the left and right buffers local before_char="" local after_char="" # Check if the cursor is not at the beginning of the line if [[ -n "$LBUFFER" ]]; then before_char=${LBUFFER[-1]} # Last character of LBUFFER fi # Check if the cursor is not at the end of the line if [[ -n "$RBUFFER" ]]; then after_char=${RBUFFER} # First character of RBUFFER fi # Print the characters before and after echo "${before_char}${after_char}" } # Bind the function to a key combination (for example, Ctrl+P) zle -N print-char-before-after bindkey '^P' print-char-before-after
