# Usage:
|
|
# <Leader>i - Insert character at cursor position
|
|
# <Leader>a - Insert character after cursor position
|
|
#
|
|
# You can use a count before the mapping to insert multiple copies
|
|
# of the same character. For example: 3<Leader>i will insert the
|
|
# character 3 times at the cursor position.
