• Add font resize shortcut:

# See https://sw.kovidgoyal.net/kitty/conf/#conf-kitty-shortcuts-layout
# Resize fonts in current OS window
map ctrl+shift+equal       change_font_size current +1.0
map ctrl+shift+plus        change_font_size current +1.0
map ctrl+shift+kp_add      change_font_size current +1.0
map ctrl+minus             change_font_size current -1.0
map ctrl+shift+kp_subtract change_font_size current -1.0
# map ctrl+shift+backspace   change_font_size current 0
map ctrl+0                 change_font_size current 0

• Add window splitting / zooming:

enabled_layouts splits:split_axis=horizontal, stack

# Create a new window splitting the space used by the existing one so that
# the two windows are placed one above the other
map ctrl+shift+o launch --location=hsplit

# Create a new window splitting the space used by the existing one so that
# the two windows are placed side by side
map ctrl+shift+e launch --location=vsplit

# Create a new window splitting the space used by the existing one so that
# the two windows are placed side by side if the existing window is wide or
# one above the other if the existing window is tall.
# map f4 launch --location=split

# Rotate the current split, changing its split axis from vertical to
# horizontal or vice versa
# map f7 layout_action rotate

# Move the active window in the indicated direction
# map shift+up move_window up
# map shift+left move_window left
# map shift+right move_window right
# map shift+down move_window down

# Move the active window to the indicated screen edge
# map ctrl+shift+up layout_action move_to_screen_edge top
# map ctrl+shift+left layout_action move_to_screen_edge left
# map ctrl+shift+right layout_action move_to_screen_edge right
# map ctrl+shift+down layout_action move_to_screen_edge bottom

# Switch focus to the neighboring window in the indicated direction
map ctrl+shift+h neighboring_window left
map ctrl+shift+l neighboring_window right
map ctrl+shift+k neighboring_window up
map ctrl+shift+j neighboring_window down

# Note: use ctrl-shift-r   to resize the current window

# Zoom on current window
map ctrl+shift+z toggle_layout stack

Tips

Increase font size

Increasing the font size dynamically seems to require to enable remote control

kitty -c NONE -o font_size=12 -o allow_remote_control=yes # Or through config
kitty @ set-font-size -- +2
