Module: awful.hotkeys_popup.widget

Popup widget which shows current hotkeys and their descriptions.

It's easy to add hotkeys for your favorite application. Below is how to add hotkeys for firefox to the previously created hotkeys_popup in rc.lua.

-- Create the rule that we will use to match for the application.
local fire_rule = { class = { "firefox", "Firefox" } }
for group_name, group_data in pairs({
    ["Firefox: tabs"] = { color = "#009F00", rule_any = fire_rule }
}) do
    hotkeys_popup.add_group_rules(group_name, group_data)
end

-- Table with all of our hotkeys
local firefox_keys = {

    ["Firefox: tabs"] = {{
        modifiers = { "Mod1" },
        keys = {
            ["1..9"] = "go to tab"
        }
    }, {
        modifiers = { "Ctrl" },
        keys = {
            t = "new tab",
            w = 'close tab',
            ['Tab'] = "next tab"
        }
    }, {
        modifiers = { "Ctrl", "Shift" },
        keys = {
          ['Tab'] = "previous tab"
        }
    }}
}

hotkeys_popup.add_hotkeys(firefox_keys)

Example of having different types of hotkey popups:

awful.keyboard.append_global_keybindings({
    awful.key({modkey}, "/", function()
      hotkeys_popup.show_help()
    end, nil, {
      description = "show help (all)", group="HELP"
    }),
    awful.key({"Shift", modkey}, "/", function()
      hotkeys_popup.show_help(nil, nil, {show_awesome_keys=false})
    end, nil, {
      description = "show help for current app", group="HELP"
    }),
    awful.key({altkey, modkey}, "/", function()
      hotkeys_popup.show_help({}, nil, {show_awesome_keys=true})
    end, nil, {
      description = "show help for awesome only", group="HELP"
    })
    -- (more hotkeys go here)
})
