---@brief [[
--- Module for convenience to override defaults of corresponding |telescope.actions| at |telescope.setup()|.
---
--- <pre>
--- General usage:
---   require("telescope").setup {
---     defaults = {
---       mappings = {
---         n = {
---           ["?"] = action_generate.toggle_registered_actions {
---             name_width = 20, -- typically leads to smaller floats
---             max_height = 0.5, -- increase potential maximum height
---             seperator = " > ", -- change sep between mode, keybind, and name
---             close_with_action = false, -- do not close float on action
---           },
---         },
---       },

--- Display the keymaps of registered actions similar to which-key.nvim.<br>
--- - Floating window:
---   - Appears on the opposite side of the prompt.
---   - Resolves to minimum required number of lines to show hints with `opts` or truncates entries at `max_height`.
---   - Closes automatically on action call and can be disabled with by setting `close_with_action` to false.
---@param opts table: options to pass to toggling registered actions
---@field max_height number: % of max. height or no. of rows for hints (default: 0.4), see |resolver.resolve_height()|
---@field only_show_current_mode boolean: only show keymaps for the current mode (default: true)
---@field mode_width number: fixed width of mode to be shown (default: 1)
---@field keybind_width number: fixed width of keybind to be shown (default: 7)
---@field name_width number: fixed width of action name to be shown (default: 30)
---@field column_padding string: string to split; can be used for vertical seperator (default: "  ")
---@field mode_hl string: hl group of mode (default: TelescopeResultsConstant)
---@field keybind_hl string: hl group of keybind (default: TelescopeResultsVariable)
---@field name_hl string: hl group of action name (default: TelescopeResultsFunction)
---@field column_indent number: number of left-most spaces before keybinds are shown (default: 4)
---@field line_padding number: row padding in top and bottom of float (default: 1)
---@field separator string: seperator string between mode, key bindings, and action (default: " -> ")
---@field close_with_action boolean: registered action will close keymap float (default: true)
---@field normal_hl string: winhl of "Normal" for keymap hints floating window (default: "TelescopePrompt")
---@field border_hl string: winhl of "Normal" for keymap borders (default: "TelescopePromptBorder")
---@field winblend number: pseudo-transparency of keymap hints floating window
