Is there a tutorial on mapping keys in Vim?

How to remove a map from a Vim file?
If the map is defined in the .vimrc or _vimrc file or in one of the files in the vimfiles or .vim directory, then you can edit the file to remove the map. Another approach is to use the ‘:unmap’ and ‘:unmap!’ commands to remove the map. For example, to remove the map for the key, you can use the following commands:
How to check if a map is defined in Vim?
To check whether a map is defined for a key sequence, you can use the mapcheck () function. Example: In a map command, you can use the mode () Vim function to get the current editing mode. But this function returns ‘n’ (normal) or ‘c (command-line) in most cases.
How to get the current editing mode in Vim?
In a map command, you can use the mode () Vim function to get the current editing mode. But this function returns ‘n’ (normal) or ‘c (command-line) in most cases. So this function cannot be used reliably from a map command to get the current mode. Instead, you should pass the current mode as an argument to the called function.
What to do with ambiguous mappings in Vim?
You can use this to put command sequences under function keys, translate one key into another, etc. See |:mkexrc| for how to save and restore the current mappings. *map-ambiguous* When two mappings start with the same sequence of characters, they are ambiguous.
Which is the default key for the local leader variable in Vim?

What’s the default value for buffer-local mapping in Vim?
For buffer-local mappings, the prefix should be used. Vim will replace this with the value set in the ‘maplocalleader’ variable. The default value for this variable is backslash (‘\\’). The is generally used in mappings defined by a Vim filetype plugin.
How to insert the result of an expression in Vim?
You can insert the result of a Vim expression in insert mode using the = command. For example, the following command creates an insert mode map command that inserts the current directory: If you don’t want to insert anything then you can return an empty string from the expression.
Which is the insert mode key in Vim?
To do this, you can use the insert-mode key which temporarily goes to normal-mode for one normal mode command and then comes back to insert mode. For example, to call the Vim function MyVimFunc() from insert mode, you can use the following map command:
