omg, I've mapped some keys to resemble HHKB layout and my fingers already glued

here's xremap snippet

- name: HHKBImitation
remap:
Ctrl_R-LEFTBRACE: UP
Ctrl_R-APOSTROPHE: RIGHT
Ctrl_R-SEMICOLON: LEFT
Ctrl_R-SLASH: DOWN
Ctrl_R-K: HOME
Ctrl_R-COMMA: END
Ctrl_R-L: PAGEUP
Ctrl_R-DOT: PAGEDOWN
Ctrl_R-BACKSLASH: DELETE

I have had Caps remapped to left Ctrl and backslash/backspace swapped, but I haven't expected those new arrow keys to be so natural

btw did I use "have had" correctly here? anyway, now I'll do my anki for today and go to bed, ni-ni fedi 
@eq for me it seems as nonexistent structure. did you meant just "had"?
@hldpnch it might feel weird, but it does exist :)
afaik it shows the effect or relevance of a past action in the present. maybe I could've just used "already had", but I was eepy and just used whatever came to mind at the time 
When is it necessary to use "have had"?

I have come across a few sentences that contain "have had". I would like to know in what kind of situations we should use this combination.

@eq oh, I see.
well, in language that has word "defenestration" this is expected.
but still english such a weird and unlogical language.
@hldpnch I don't know,,, I don't even think that much about it really, I just use it. I don't mean it's perfect and I fully understand why english might seem a bit odd, but I feel like that goes away over time as you get more exposure to it
