Lowest number of keystrokes to modify part of a line

Hi,

I'm Italian hence knowingly lazy.

I have a file that I use as a log for my morse learning.

The structure is:


qrq Wed 26/10 11:18
Groups Thu 27/10 20:00
WT Thu 27/10 21:37
qrq2 Thu 27/10 10:24
morse Fri 28/10 20:17
qrq Fri 28/10 22:15
Groups Sat 29/10 19:46
WT Sat 29/10 21:21
qrq2 Sun 30/10 18:48
morse Sun 30/10 22:07[x]
qrq Mon 31/10 10:19
Groups Mon 31/10 19:42

See that [x]? That's where the cursor is.

I want to modify the line just below that (starting with qrq), remove
that timestamp and put a new one.

The timestamp is mapped to 'mydate' :

$ grep mydate .vim/vimrc
iabbrev mydate <C-R>=strftime("%a %d/%m/%Y")

I want to find the lowest number of keystrokes I need to modify that
timestamp.

What I'm doing at the moment is:

[w] [w] [R] cwd [:wq]

That is: one word forward, one word forward, Replace to the end; save
and quit, but I wonder if there is a lazier and more elegant way.

M. v. g.

Re: vim airline too consumption starting time

Bonjour Nicolas,

I don't want to highjack your thread. But I have the same problem: vimr or neovim are starting for the first time after restart of my macOS very slowly (more than 20 seconds). But the command `vimr --startuptime vimr.log` does not work in my shell. Same with `neovim` and also with `sudo` ... The command works seamlessly with vim; but here I have no starting problems, because vim has nearly no plugins. 

Perhaps could somebody could help here?

marek

ps: should I open an own thread perhaps?

Re: pb with nnoremap an imported vim9 defnot loaded

Hi Salman,

I copy paste this from $MYVIMRC

nnoremap n n<ScriptCmd> thatHelp.HLNext(80)<CR>
nnoremap N N<ScriptCmd> thatHelp.HLNext(80)<CR>

it's in reference to another post https://groups.google.com/g/vim_use/c/_U2ne7QlOWc/m/7pUuGJ2BAwAJ.

I cannot or don"'t know how to test it through command line because it calls an imported vim9 def func.

...n <ScriptCmd>th... defines a mapping for n that then executes a script command and is probably what you want

As an aside, the function you defined is technically correct, though inefficient in a few things, but that's not likely to be the cause of your woes.

Re: How to incude '/' in search(find) string on the fly

Glad you found a solution. I've just become really accustomed to escaping the slash so don't even think about it any more.
