Just made my day a whole lot easier!

Echoing the message above, really good config to start with, thank you.

That should go into official documentation. Plenty of people like me have tmux keybindings hardwired into their brains

Thank you so much for this snippet! Saved me an hour 🙌

allow repeating J H K L when resizing:

	{
		key = "h",
		mods = "LEADER|SHIFT",
		action = wezterm.action.Multiple({
			wezterm.action.AdjustPaneSize({ "Left", 5 }),
			wezterm.action.ActivateKeyTable({ name = "resize_pane", one_shot = false, until_unknown = true }),
		}),
	},
	{
		key = "j",
		mods = "LEADER|SHIFT",
		action = wezterm.action.Multiple({
			wezterm.action.AdjustPaneSize({ "Down", 5 }),
			wezterm.action.ActivateKeyTable({ name = "resize_pane", one_shot = false, until_unknown = true }),
		}),
	},
	{
		key = "k",
		mods = "LEADER|SHIFT",
		action = wezterm.action.Multiple({
			wezterm.action.AdjustPaneSize({ "Up", 5 }),
			wezterm.action.ActivateKeyTable({ name = "resize_pane", one_shot = false, until_unknown = true }),
		}),
	},
	{
		key = "l",
		mods = "LEADER|SHIFT",
		action = wezterm.action.Multiple({
			wezterm.action.AdjustPaneSize({ "Right", 5 }),
			wezterm.action.ActivateKeyTable({ name = "resize_pane", one_shot = false, until_unknown = true }),
		}),
	},

# then 

config.key_tables.resize_pane = {
	{ key = "h",      mods = "SHIFT",          action = wezterm.action.AdjustPaneSize({ "Left", 5 }) },
	{ key = "j",      mods = "SHIFT",          action = wezterm.action.AdjustPaneSize({ "Down", 5 }) },
	{ key = "k",      mods = "SHIFT",          action = wezterm.action.AdjustPaneSize({ "Up", 5 }) },
	{ key = "l",      mods = "SHIFT",          action = wezterm.action.AdjustPaneSize({ "Right", 5 }) },
	{ key = "Escape", action = wezterm.action.PopKeyTable },
}
